Well the reason I disliked ME3 (and most of the community I believe) is because of the ending and how it made everything that occurred within the three games completely useless and irrelevant. I'm saying ending because there's such negligible differences between the different endings and they all bomb just as hard.

When I was playing Gunz around 2 years ago, it was full of hackers. Also, yeah, the community is awful, but the game's still pretty fun if you can find some friends to play with like I did.
