I barely heard of the Wizardry series, and had Bane of the Cosmic Forge screenshots been absent from Gamebase Amiga (looking like an OK DM clone, but apparently ridden with bugs), I think I would have completely overlooked it.
Too bad, the programmers of these games didn't try harder to port it to a wider range of platforms. Personally, I don't think I could play an RPG with inferior graphics than, say, Ultima IV except for text & graphics adventurers, which is a wholly different subgenre.
As for the review itself, you're right not too show more modern RPG video footage before Proving Grounds runs, because it would make the game look even more 70s'ish
What's that dunjonquest you're evocking btw ? Is it spelled correctly ?
