Its been a lot of years since the seventh generation has ended.This is one of the last good crossgen games availaible.Its a great game as expected by kojima and its graphics on ps3 are fabulous.Although there are some framerate dips but thry wont undermine the experience.
You dont need to know the whole story of the series to play the game a little context may help from internet
Overall great product
if somebody is still on ps3 u can buy it and trust me you wont regret it later.:)
