Actually, Its 5 hours of cutscenes/story and 5 hours of gameplay/Hack & Slash. It really doesn't have any reason to buy it but Raiden fans or for fans who brutally hate the new Devil May Cry, since Platinum Games are the same guys who made the origional Devil May Cry 1-3.
Yeah I'm getting it most due to it looking fun and been waiting for it for a long time. However I'll buy it once the prices goes down. Metal Gear games get cheap pretty fast for some reason. More interested in Ni no Kuni as a ps3 buy for me. I would not mind Ground Zero on Wii U. I think a regular MGS would work well
