Marvel Ultimate Alliance. Holy shit. I just installed it this morning and I've already missed half a day's worth of work.

Screw Activision, though. Cheap force feedback gamepads will not work and will crash the game at startup (I've seen that there are a lot of complaints about this problem online, not just with my particular brand of pad). Had to uninstall my drivers and use the one that came with windows, which means no force feedback.

The game itself is basically just X-Men Legends II with more polish and different skins. In fact, turning off advanced lighting makes the game look like X-Men Legends II. But that advanced lighting thingie is awesome, makes the graphics look halfway photorealistic, with the disadvantage of effectively reducing the framerate on crappy videocards.
