Not really getting the hate for Metal Gear Rising, but feel free to share what all you don't like about it.
It's made by the same studio that made Bayonetta, Vanquish, Madworld, previously made God Hand and Okami, and the director was behind the first Devil May Cry. Keep in mind it's not a Metal Gear "Solid" game, this takes place after MGS4 as well, and Snake shouldn't live out the last years of his life fighting.
Recent gameplay videos have actually shown that there's stealth elements in Rising as well, and the combat looks pretty crazy. I trust that Platinum Games knows what they're doing, from my experience they have yet to have a bad game release.
Still, I think E3 was overall pretty terrible this year really, from that...hilariously bad Harry Potter Book game to Microsoft: Now with 98.5% less games.
I should add that first two installments of the series weren't Metal Gear "Solid" titles either, yet the 'Solid' titles still built off of the elements present in those games as well.
Except, I'm not one to talk, I'm the one who actually liked Resident Evil 4 & 5.
