This game is much better than many that have come out in the past 5 years. If you like TF2 this is very similar. It is a team based objective game type. I don't see where the reviewers or people here are having issues. It runs pretty smooth for me right out of the box.
If you don't play a game for a good week how can you possibly have learned all of the mechanics and game play techniques?
