It's almost as if he's proposing they offer a 2D + 3D fighting experience in one game (I cant even wrap my head around how that would work). Either that or he's just missing the point of Street Fighter X Tekken entirely.
The second and third paragraph also make it sound like the 2D fighting genre is dead and the more realistic UFC/Boxing games are taking its place, which couldn't be further from the truth (See record crowds attending EVO and weekly/monthly events streamed online to over 20-30k viewers per pop).
Normally I find GP reviews pretty close to the mark, but this honestly feels like it was written by someone completely out of the fighting game loop. I mean there's not even a mention of Pandora mode, which is basically the entire point of the story and a significant gameplay mechanic.
