This is just a fucking spin-off. Not even Kojima seems to take this seriously. Look at his declaration on the MGS Peace Walker, for PSP: "This is a true sequel to the original chronology. It follows the know story and it's not just a rip-off", a clear reference to this outrageous bullshit that is MGS Rising.
It's not even Tactical Espionage Action, it's fuckin Lightning Bolt Action... There'll be no sneaking, just Raiden slashing everything with his sword like on a Ninja Gaiden
I feel sorry for those who said "know there's no need for a PS3", like if this stupid game that's not even following the original series and only takes the MGS name for financial motives, would make all the difference on the choice beetween the two consoles
MGS4> EVERYTHING ELSE..... IN THE WORLD
