Recommended: FarCry3
I highly recommend that you check out FarCry3. It's not the greatest game of all time, but it is very enjoyable. The interface feels like a terribad port from a console-based game. The interface simply sucks, there is no way to deny it (e.g. press and hold "E" to interact with objects, the jumping/ climbing "Spacebar" is st00pid, and the "Mash C, Space, W" is beyond retarded and comes straight from X-box. Also, the stealth elements of the game are a direct rip-off of Thief and Hitman, and they are totally dumbed-down for 12 year old gamers. But even with these problems, the game is still pretty good, and will hold your interest for 60+ hours, if not more. Get it today.
