ME3 - Kind of wish the game had a better intro, while I get they wanted to start the game with a Hollywood style spectacle much like ME2, I feel like enough things have happened between ME2 and 3 to deserve a brief narration explaining what happened to Shep in that time frame.

The cover controls are also a bit wonky, I got killed a few times during the "dodge the turret while slowly moving from cover to cover" segment on Mars because Shep would either reach a cover point and forget to duck but still be stuck to the object or I would have the opposite issues where Shep just never recognized the wall to begin with and starting running circles around it trying to fin the right spot on the wall to cover which was 70% of the time on the wrong side of the wall...
