I enjoyed Enslaved. It starts out kinda slow and obvious, but quickly develops into a Prince of Persia kind of gameplay, where the player needs to figure out the best way to get from point A to B while dispatching many types of robotic enemies along the way. The story was okay, but I expected better. It was written by Alex Garland (Sunshine, 28 Days Later, The Beach), so I may have gotten my hopes up in that regard. It was worth playing through once and beating, in my opinion, but I wouldn't buy it. There's little to do once you beat the game, and you can feasibly beat this game in a few days.

As for the other two, I heard good things about DS2. I haven't played it and have only scratched the surface of the first game, but certainly see the appeal to a sci-fi survival horror game. If someone were to tell me that survival horror is their game of choice, I'd recommend Dead Space... or maybe that they wait for the re-release of Code Veronica and RE4. I'll get around to it when I'm in the mood for that type of game, but again, not something I'd buy.

I was pretty excited for Brink. It sounds like Mirror's Edge meets Team Fortress. Unfortunately it came out with poor reviews and complaints about not enough levels, objectives per level, and not enough difference between each of their four classes (Soldier, Medic, Engineer, and Operative). I really like the sound of the setting (floating utopian city split into two factions) and the parkour-style movement, but due to mixed reviews, I'll be renting this first to see what I think.
