7. Dragon Age: Origins
Bioware's unholy struggle with Bethesda to be crowned as top dog among RPG developers really kicked with Dragon Age: Origins, a conventional fantasy-RPG every bit as epic in its scope as an Elder Scrolls game. Its game world was so huge and varied, featuring countless towns and immaculately realised geography, that its dungeons, to be fair, never took centre stage. But nevertheless, they were huge, atmospheric and involving - and the game, along with its successor, Dragon Age II, really cemented Bioware's lofty reputation.
8. World Of Warcraft: The Burning Crusade
We could have put Blizzard's original game or any of its expansion packs into this round-up, but The Burning Crusade received particular acclaim for the quality of its dungeons. Blizzard clearly put a lot of effort into TBC's dungeons. Even the smaller ones offered much more of a challenge - and were much moiré memorable - than before, and while they were designed for groups of 5 to 25, you could clean most of them out with a group of 10 players, rather than the unwieldy near-20 required previously. One suspects that many people developed a lifelong love of dungeons in The Burning Crusade.
9. The Elder Scrolls IV: Oblivion
As with Skyrim, Bethesda Softworks didn't skimp on the dungeons when it designed Oblivion. Although there weren't as many as there are in Skyrim, if you cleared them out, left them for a few days and levelled up a bit, you could go back to them and find that everything in them had respawned, complete with trickier enemies. Dungeons with replay value -- now that's a great concept. Small wonder that Oblivion was hailed as the best conventional RPG ever when it came out in 2006. We reckon it still holds up pretty impressively, even against the best RPGs that modern technology can buy.
