AC is an ok game, but halfway through it I was already tired of it. That particular Batman formula wore itself out so quickly for me, the colors, the Unreal as hell models, the combat engine having things tacked onto it to make it seem more complex than it was. (All the finisher stuff and quick batarangs/batclaws/etc made something incredibly simple seem like a complete mess. I thought the Sleeping Dogs combat style was a much better take on it, but since they came up with it initially in Bully/Warriors, that makes sense. A lot of the bosses in AC felt like they were thrown in because they weren't in the last game and they had to meet some kind of quota. Everything about the Freeze encounter past the meeting was so underwhelming.
Never even played Origins.
