CS:GO. Well, I have a mixed feeling with it. It's not a easy game for most players, but I hear it is addictive. I never could get into it myself, though, I'm pretty decent at the game. One of the main problems I myself had with it is the unability to respawn in competitive, which ruined my fun until I got used to it, no fun waiting around, huh? There are many problems, or things I dislike, but its up to you really. I'd not reccomend it myself.
