Assassin's Creed 3 - Story was actually ok, I enjoyed the history romp. But the gameplay got so boring, repetitive, and pointless. The sim farm stuff wasn't that great either, though the hunting and forest parkour wasn't too bad. The ship battles were ok, but not as ragingly awesome as everyone said they were, which is why I put it down at this point. They just took out all the best parts of the previous games, with forced stealth, ridiculous assassination missions, and lame combat which forces you into cheap tricks.
Dead Space 3 - Fuck you, for taking one of the best survival horror games of that generation into the cringiest, shittest territory. Stupid story, dumb-as-a-bag-of-nails protagonist AND antagonist, badass chick character reduced to a damsel who you have to save *multiple* times, stupid game mechanics, zero horror, and above all, microtransactions.
Need for Speed - Didn't do anything wrong really, just stopped appealing to me. I got more into the realistic driving simulators and just wasn't interested in cop chases anymore. However, I was about ready to jump back in at NFS 2016, but when I heard it was online only, and didn't support steering wheels (maybe they do now, I don't care), that's where I said nah fuck off. Pity, because I practically grew up on this series and honed my driving sim skills from it since I was a kid, back in 1994. Played every single one up to the Shift series.
Battlefield 3 - Because of the Origin shit. Not that I mind Origin as such, the more competition to Steam the better - but the forced online and other EA practices. If it's gotten better though I might give it a crack again eventually, Battlefield 1 looks pretty good value for the money, unlike Battlefront.
