Me? I’d be terrified about it, but I’m going to pick Ultima 7. Knowing full well that some folks will accuse me of heresy, what I’d like to see changed beyond upgraded technology and UI would be the combat system. Something more like “turn-based with pause” from the Infinity Engine games (Baldur’s Gate, etc) with better AI and a slower pace so things like actually casting spells in combat would have a chance to succeed. Since nobody ever seemed to feel that combat was really that good in the first place in Ultima 7, I don’t think that sort of thing would violate the spirit of the game, or the series. I would also like to see stat-check style mechanics supplement (not entirely replace) the elements of the game that were more twitch-driven… dodging fireballs and that kind of thing. This way even those who prefer a more thoughtful pace in their RPGs wouldn’t get badly penalized for not playing it like a an NES game. And really, what made Ultima 7 work so well was the world and the story, not the RPG mechanics… which to me always felt a little half-baked.
