I was reading about Daikatana and it looks really intresting in this regard. I know it's a horrible game.
Games that I can think of that fit the billDaikatana is composed of twenty-four levels divided into four episodes. The number of maps per level varies, but is generally about three. Each episode represents a different location and time period: futuristic Japan, ancient Greece, the Dark Ages in Norway and near-future San Francisco. Gameplay tends towards fast-paced combat, although an attempt at introducing problem-solving elements was also included.
Unreal Tournament
Hexen+Heretic
Bioshock
Team Fortress 2 has an intresting cartoony look but the levels themselves aren't very intresting
I've played some old, relatively unknown FPS games that were quite creative/unique looking like Killing Time, PO'ed and Escape from Monster Manor, but they were gameplay wise so bad that there's no point listing them.
