The expansion to Titan Quest. If you dig Diablo-style hack-and-loot action, but don't feel like visiting Sanctuary, give this one a shot. Nine Masteries (classes) to choose from, along with a Dual-class system allows for different combinations of powers; no shoe-horning of your abilities or skills, play how you want to play.

This one's highly recommended.

Outstanding game, great narration, soundtrack is one of the best I've ever heard. If you have the means, I highly recommend it.

I cannot recommend this game enough. All the FPS fun without the immediate death you come to expect from such a genre. The RPG factor allows for both randomized loot and improvements on skills, giving you an edge. Save a couple of bucks and get the GotY edition, as the DLC is more than worth it.
