Defenders of Oasis on Game Gear: Sega’s 1992 Arabian Nights RPG, and Why Its Japanese Name Is the Only Thing That Finds It

Defenders of Oasis went on sale in Japan on 18 September 1992 as a Game Gear cartridge at 5,500円 before tax, under a title that shares not one word with the English one: シャダム・クルセイダー 遥かなる王国, Shadam Crusader: The Far Kingdom. Sega CS2 developed it and Sega published it, and it is one of the very few original role-playing games built for the Game Gear rather than ported to it.

This is an entry in a series about games that never got a second part, and this one is not a curiosity or an argument. Defenders of Oasis was liked at the time, charted for four months, and is still named as the best RPG on its console. It simply never had a follow-up — and it is the hardest game in the series to search for, because the two shops that have it want two different spellings of a name you have probably never typed.

• Japanese title: シャダム・クルセイダー 遥かなる王国, developed by Sega CS2, published by Sega
• Game Gear cartridge: 18 September 1992 · 5,500円 before tax · 4 megabits · one player
• Catalogue number: G-3404 — and for once it is in the Media Arts Database, with a barcode to match
• An Arabian Nights RPG: overhead view, turn-based party combat, villages with shops and inns — and an autosave, in 1992, on a handheld
• Game Gear only: no Master System version exists, so no other-hardware copies turn up in Japanese shop searches
• Abroad: North America December 1992 at $39.99, Europe and the UK May 1993 at £34.99, all under catalogue number 2503
• No sequel: what followed was the Nintendo 3DS Virtual Console, 18 July 2012 in Japan and 20 June 2013 in the West
• Buying it: Suruga-ya wants シャダム; Buyee wants シャダムクルセイダー without the dot. The shop’s own copy was ￥9,300 and a marketplace seller on the same page had one at ￥1,540 (prices as of 21 September 2026)

What is Defenders of Oasis, and how does it play?

You are the Prince of Shadam. English Wikipedia lays out a plot that leans hard on its source material: the hero Jamshid once sealed away the dark god Ahriman and founded the kingdom of Shadam, and a thousand years later Ahriman works his way back by steering the Yufurat Empire into hunting the three holy rings that sealed him. When the Empire attacks, King Shadam VII hands his son a ring and sends him running.

What follows is a proper role-playing game, not an action game with menus. Wikipedia describes it plainly: the Prince “is initially solitary, but forms a party including three other characters over the course of the game”, the view is overhead, and the world is villages and castles where you talk to people and pick things up. Every village has at least one shop for weapons, armour and accessories, and somewhere to rest and restore hit points and spell points. There is a status screen for equipment and spells.

Two things make it feel unusually finished for a 1992 handheld. The first is the autosave: “ongoing game progress is stored via the autosave function”, which in a year when its shelf-mates were still handing out passwords is a real difference. The second is the setting, which is not generic fantasy with a desert level. The names are the names: Jamshid, Ahriman, Zahhak, Fereydun. A jinn in a lamp declares the Prince his new master. A ship’s captain has a son called Sindbad. You are playing through One Thousand and One Nights with a party menu.

Which release is the Japanese cartridge, and what is its code?

For the first time in this series, this section is short, because nothing is wrong.

The Japanese Game Gear cartridge is catalogue number G-3404, and four independent sources say so. The Agency for Cultural Affairs Media Arts Database has it as row M726707 with schema:productID set to G-3404 — a field that was simply empty on the last three games we covered — plus a barcode, 4974365134044. Sega’s own Game Gear software list gives the same code in the same row as the date and price. Suruga-ya’s trade-in page prints 型番 G-3404. Sega Retro’s release table gives G-3404 for Japan.

That is worth saying out loud because the previous entry in this series had the opposite problem: Sega’s published list gives Ax Battler a catalogue number that belongs to a Donald Duck game. We went back and re-parsed all 135 rows of that list for this article, and G-3306 is still the only number in it that appears twice. The G-34xx block is clean, and Suruga-ya’s own index agrees: G3403 returns アーリエル, G3404 returns this game.

That record is also unusually complete: revised on 2 March 2026, it measures the box at 10.8 × 9.5 × 2.1 cm, the cartridge at 6.9 × 6.6 × 1.1 cm, and counts the manual at 48 pages.

The name is the messy part. Three spellings are in circulation, and they differ by a single character. The Media Arts Database and Sega’s own Virtual Console page write 遥かなる王国. Sega’s software list and the database’s Virtual Console row write the variant 遙かなる王国. And Suruga-ya files its stock as シャダムクルセイダー — no interpunct at all. Which of those you type matters in one place and not another, and the difference is the whole of the search section below.

What was the list price, and what does it cost now?

Three sources agree on the list price and none of them disagree: the Media Arts Database records [5,500円（税抜）], Sega’s list prints 5,500円, and Sega Retro’s release table gives ¥5,500. Suruga-ya shows 定価：￥6,050, the same number with today’s 10% consumption tax: 5,500 × 1.1 = 6,050. The figure to quote is 5,500円 before tax.

At 5,500円 this was an expensive Game Gear game. Most of the library sat at 3,500円 to 3,800円; four megabits and an RPG’s worth of text put this one near the top of Sega’s own price list.

Now for the part that will save you money. On 21 September 2026, Suruga-ya had one copy in stock. The shop’s price on it was ￥9,300, and one line below, on the same page, the marketplace read ￥1,540 across seventeen used copies (prices as of 21 September 2026).

That is about a sixth of the price, and it is the widest gap we have measured in this series. Ax Battler was ￥12,100 against ￥2,830 and Royal Stone ￥5,900 against ￥4,540 (prices as of 21 September 2026). Here the shop price is not in the same conversation as the seventeen copies sitting underneath it.

The shop’s own copy comes with Suruga-ya’s condition grading and its returns process, which is worth paying something for. It is probably not worth paying ￥7,760 for without deciding to.

Was Defenders of Oasis any good?

Yes, and unusually for this series that is not a contested answer.

GamePro scored it 15.5 out of 20. In Sega Force, Paul Wooding praised the variety of items and characters and called the plot “highly original and entertaining”, while Adrian Pitt called the game “instantly playable” and “the most user-friendly RPG I’ve ever played”, with visuals “well defined and colourful” and a soundtrack he rated “some of the best I’ve heard spout outta the Game Gear”. It sold, too: English Wikipedia records that it stayed inside the top-ten chart for four months after release.

The verdict has held up. Damien McFerran of Time Extension put it on his list of the best games in the Game Gear library and called it the console’s best RPG, in a library that had very few of them, praising the mix of exploration, turn-based combat and the One Thousand and One Nights storyline.

That is a different shape of story from the last entry in this series. Ax Battler got 39% from Mean Machines Sega and 5, 5, 5 and 4 out of 10 from Famitsu, and the absence of a sequel reads as a verdict. Here it does not. This game was well made, well received and commercially fine, and it still ends where it ends.

Why was there never a second one?

There is no answer in the record, only the absence. English Wikipedia’s article names no sequel and no successor. The Media Arts Database has two rows for this title and nothing else: the 1992 cartridge, and the Nintendo 3DS Virtual Console release of 18 July 2012.

We also checked the two Sega download services where the company quietly kept older properties alive, because that is exactly where this series has been caught out before. It is on neither. Sonic Cafe, the i-mode subscription service Sega ran from 2001, does not list it; nor does Game Toshokan, the Mega Modem download service that distributed thirty-nine titles from November 1990. We searched both full title lists for Oasis, Shadam, Crusader and Defender and got nothing in either.

So the line is: one cartridge in 1992, one re-release twenty years later, and that is all there has ever been. The Virtual Console version is long delisted, which leaves the cartridge.

Can you buy it today, and which copy should you buy?

Easily. On 21 September 2026 Suruga-ya had one copy in stock plus seventeen on its marketplace, and the Buyee search showed results: 10. This is the most available game we have covered in this series.

Suruga-ya holds six separate entries once you show sold-out items, and the differences between them are the decision:

• シャダムクルセイダー 遥かなる王国 — the complete one, in stock at ￥9,300, with marketplace copies from ￥1,540 (prices as of 21 September 2026)
• …(箱説なし) — cartridge only, no box or manual. Sold out
• …(状態：箱(内箱含む)状態難) — complete, but the box is in poor condition. Sold out
• ランクB)… — the shop’s B grade. Sold out
• [説明書のみ]… — the manual on its own. Sold out
• [外箱のみ]… — the outer box on its own. Sold out

The last two are not games. They exist so someone rebuilding an incomplete copy can buy the missing piece, and in a list of results they read as cheap listings of the cartridge. The bracket at the front of the title is the tell: 説明書のみ is a manual, 外箱のみ is a box. Given the manual here runs to 48 pages, a complete copy is a meaningfully different object from a loose cartridge.

On Buyee the search showed results: 10 (this game: 10); the listings are described variously as boxed with manual, software only, tested and working, or missing the manual.

One thing you do not have to worry about: other hardware. This game was Game Gear only. Dragon Crystal, another Game Gear game from the same period, has an overseas Master System version that turns up inside Japanese shop searches and has to be filtered out by eye. Here there is nothing to filter. Western Game Gear cartridges exist — North America from December 1992, Europe and the UK from May 1993 — and Japanese shops label those 海外版, but none appeared in our measurements.

How do you search each shop for it?

This is the game where the two shops disagree with each other, and the disagreement is one character wide.

Suruga-ya: シャダム is enough, and punctuation does not matter. Four spellings — シャダム, シャダム・クルセイダー, the full title with 遥, and the full title with the variant 遙 — all return the same results: one listing in stock, six with sold-out items shown, and all six are this game. The shop absorbs the interpunct and the character variant. Use the short form.

Buyee: drop the interpunct. シャダムクルセイダー without the dot shows results: 10 (this game: 10). シャダム・クルセイダー 遥かなる王国 with the dot shows results: 4 (this game: 4). Buyee does not absorb the punctuation the way Suruga-ya does — it is matching characters inside titles that sellers typed by hand, and most of them did not type the dot. Results with the dot: 4; without it: 10 — for no reason other than a symbol.

Buyee: do not use シャダム on its own. Its results: 20 (this game: 9). The rest are Dune — the Emperor is Shaddam — along with Gosei Sentai Dairanger discs and a Shazam! DVD. Suruga-ya’s short form is Buyee’s trap.

Neither shop wants the catalogue number, and this time Suruga-ya does not either. On the last three games in this series the hyphenless code was the precise search at Suruga-ya. Not here: G3404 shows results: 3 in stock (this game: 1) and 13 with sold-out shown (this game: 2). G-3404 with the hyphen is the usual disaster — 323 listings in stock, 723 with sold-out shown, none of them this game on the first page, because Suruga-ya splits the code at the hyphen. On Buyee, the search for G-3404 showed results: 7 (this game: 1), and G3404 returns 366 with none in the first thirty.

The English title is worth nothing at either shop. Defenders of Oasis returns zero results at Suruga-ya and zero at Buyee. That is now four games in a row in this series where the Western name finds nothing in a Japanese shop, and it is the single most useful thing to know about buying Japanese games from abroad: the shops index what Japanese sellers and Japanese cataloguers wrote, and neither of them wrote your title.

Why search Kataban for this one?

Because the catalogue does the four things the shops refuse to.

Checked in a desktop browser on 21 September 2026: Defenders of Oasis returns two results — the 1992 cartridge and the 2012 Virtual Console release — where the same words return nothing at either shop. G-3404 and G3404 each return the cartridge, because the Media Arts Database supplied the code and the catalogue strips punctuation before matching. シャダムクルセイダー without the dot and シャダム・クルセイダー 遥かなる王国 with it both return the same two rows. And the variant 遙 reaches the Virtual Console row, which is the one filed under that character.

So whichever of the three spellings you met first, and whether you met the game as Defenders of Oasis or as シャダム・クルセイダー, the catalogue lands you on the same cartridge — and then tells you that the two shops need two different words. On a Japanese shop shelf the kana to look under is シ.

Not every game without a sequel is a game that failed. This one was reviewed well, charted for four months, and is still called the best RPG on its handheld. It got one cartridge, one re-release, and nothing else in thirty-four years. If you want it, it is G-3404, the manual is 48 pages, and the copy you should be looking at is almost certainly not the first price on the page.
