I'd go with Raiken and suggest payday 2.

Get it on steam plus some friends, the game is easy to learn and kinda hard to master depending on the difficulty you're playing in
the teamwork is 100% NEEDED so it gives you a really good gameplay when playing with friends w/ voIP and etc. You can just go killing the cops and stealing shit, or something even harder, which is trying to steal without having any alarm activated.

If you have good friends to play with, i'd say its a must-buy.
