Great game. My brother plays it a lot. I haven't really played much cuz my laptop's too laggy for it, but what I HAVE played gives the impression of a good game.
I've never played it. I sat and watched my brother play it the day he introduced me to AoT, though. My brother said it's hard to play with a standard mouse and is loads easier with one of those gaming ones with loads of different buttons on it, so I just decided not to bother and just watch videos of other people playing it instead.
