I can recommend every Bullfrog game dos or not . All of them are pure genius.
Some examples:
Magic Carpet: fly around on a magic carpet over a beautiful 3d world technically years ahead of its time.

Populous: You are a God, fighting against other gods in a celestial game of conquest..

Syndicate + Syndicate Wars: two sinister forces battling for world domination. The second one never gets old (for me)
Amazing engine (totally destructible environments!) Superb atmosphere (hearing those cyborgs breath still gives me the shills.
One of the best soundtracks I have ever heard.

Dungeon Keeper: It's good to be bad. Really, really good. One (two) of the best games ever created. I still play the second one at least once a year.

A shame Peter Molyneux seemed to have lost his gift
