Bullet Hell game that uses your music to send waves of enemies at you. Good, but you're gonna want the Ultra expansion as it adds a whole lot more enemies and depth to the game. Oh, and not good for people who have trouble with bright flashing lights.

A very nice (if buggy) action-RPG, similar to Mass Effect but with the added element of stealth.

Alpha Protocol has one of the best dialogue systems I've seen in an RPG to date. Rather than making you choose between "White Knight Good" and "Kitten-Eating Evil", you're given three personality options when conversing with characters: Suave, Aggressive, and Professional. Different characters are impressed with various responses: some are impressed/cowed by an aggressive approach, while others prefer the more conversational suave approach. Each response style also has it's downsides: you can easily piss someone off by being too casual or frigid. Each conversation matters too, as they can unlock support in missions or gain you valuable intel.

It's like Civilization, only a hell of a lot more complicated. And it has an actual world map as opposed to hexagons/squares.
