Nah. Not that. It was a good game, but not one of those games that would keep me coming back to it, like Tekken or Soul Calibur.
I stopped playing Tekken since 3 (i'm serious, I played Tekken 3 a lot on my PSone) and then I played Tekken 5... it didn't keep me coming back to play Tekken 6. The only thing recently that made me change my mind is Street Fighter x Tekken.
But anyway, about the artwork... it's great, really, it's just great! However, it's generic and not an original design idea like it should be but I like the fact they focused on Ryu and Akira's appearence on the cover.
