Whatever happened to action-RPG FPS games, anyway? The popularity of System Shock and Deus Ex should have yielded a slew of imitators that last to today. But the last one (and only that I know of, not counting its predescessor) we got was Vampire: The Masquerade: Bloodlines. The Deus Ex sequel dropped the RPG elements, and I'd bet Bioshock has too.
