My quick review of Revengeance: pretty lame, so far. You go in expecting Metal Gear, but what you get is Bayonetta (of course, if Bayonetta is what you like, then you're all set). It's all overblown cinematic histrionics with incomprehensible action gameplay. It's just too fast--your character has something called "Ninja Run", which is supposed to be some sort of amped-up parkour thing, but he just blurs over everything so fast that you don't get the sense that you are really needed for anything. You could replace him with Sonic the Hedgehog and none would be the wiser. And why do all Japanese animators insist that super bad-ass heroes must sprint bent-over? I guess it looks good on the box cover, but anyone who has ever watched the Olympics (or um, gone outside to play) knows that sprinters run bolt upright. It wouldn't be so bad if "Raiden" didn't dart around at mach 3, but with him zig-zagging in tight little circles it just feels awkward and looks ridiculous.
On the plus side, the cinematics are fairly short.
