As probably the only person in here who owns MCC, your guys assessment is way overblown. For two or three weeks multiplayer didn't work. Period. That sucked and was a major

up on their part. But after that it did work, it just took longer than most games to find a match. Within another week or two another patch came out and you could find a game much easier. I've had 0 problems with it since. It's actually been my most played game of the holiday releases by a large margin.
I'll vote Kinect only because we all knew it was bullshit from the get go (just like always online was required). Doesn't bother me, though. I like Kinect implementation in certain situations.
Edit: And I've said it before, but the redone Halo 2 campaign is amazing. Definitely my favorite remaster/remake to be done by anyone. That worked day 1.
