It kinda seems like people are acting like there are a ton of GOTY contenders... doesn't it really just boil down to The Walking Dead, Journey, and Far Cry 3? That's not going by only my opinion alone, since I didn't play Journey and while I think Far Cry 3 is fun, it's not hugely different from the past games and the story/ending aren't very good. Even those three games don't seem that great, it's more "least worst" than best. It's not like this is Red Dead vs.ME2 vs. Limbo vs. Bayonetta, and other good/great games... or last year's Saints Row 3, Portal 2, Skyrim, Witcher 2, Uncharted, Zelda, Batman, BF3, etc.
Personally, I think ME3 is still easily one of the best games of this year, if not the best, even with the the horrible ending the rest of the game was great and the multiplayer was surprisingly good, but I know most "official" lists are going to ignore it because of the ending. If someone does think this was a great year I'd love to know what games they played, since I played everything big and they all have major, almost game breaking, flaws.
Some of my bigger disappointments were:
Halo 4: It was fun and I liked humanizing chief, but it has some of the worst mission design I've ever seen since the game is literally "press the button" or drive a vehicle.
AC3: Connor was boring, but Haytham was great, which makes Connor seem even more lame. Also so many historical events was a bit cheesy. Horrible menu system, no fun side missions, and money was pointless.
Borderlands 2: Silent protagonists come off as lazy 90% of the time, still no real customization, soul, or heart... just dumb fun, which is fine.
Ghost Recon: Too mainstream, no squad mechanics makes it like any other shooter.
RE6: Enough said already.
