Never played any of those games, and I've never even heard of most of them., so that goes to show how well they're doing. Assassin's creed I've always hated since I played the second game in the franchise (never played any others), but I won't discredit a game simply because I don't enjoy it.
Rainbow 6 Seige is a realllllllly bad example. I don't know how old you are, but if you played Rainbow 6 Rogue Spear back in the late '90s, whatever destructible physics they've added has come at the loss of everything else that made the franchise great. No single player tactical campaign in a Rainbow 6 game? Are you kidding me? You might call that innovation, I just call it sad.
