Have you tried FF12? I thought it was a million times better than 10.
I haven't gotten around to trying 13 yet, I'm really excited to. I've been addicted to the series since the very first game.
I also maybe just from an artistic perspective can't get enough of the Assassin's Creed games. They're so beautiful. I barely even play them. I just climb to the top of a tower and look out over the city.
