I agree, Street Fighter IV is way too overhyped. I love the Street Fighter franchise ever since Street Fighter II (yes i'm pretty old as well), but I seriously can't see why SF IV got such high scores, while they haven't changed anything actually to the gameplay.
It's still button mashing, jumping and spam moves. Single player is ridiculously poor and short compared to for example a Soul Calibur 1 or 2. Sure it has a fresh look with the new graphics engine, but this game could have been released way earlier as well. It feels as if it's not finished or something.
I find it hard to believe that reviewers rated Killzone 2 a lower score due to it's lack of story and "not bringing anything new to the genre" (wait, what!?), while Street Fighter is more generic then any other game out there, yet it got praised with 90's and 100's. A bit weird if you ask me, because if you look at the total picture of that game, it's really not worth that score when having these critical reviewer points next to you on a paper.
Don't get me wrong Street Fighter IV is a great game, it's fun to play, but everything what Street Fighter IV did, any other fighting game such as Tekken or Soul Calibur did it better. It's that I could get SF IV for just €30,-, because I wouldn't have spend €65,- on it.
