Don't worry he'll hate MGS4 and trade back for an Xbox360 when he sees the light.
You have to play the first 3 to really understand what the heck is going on.
Edit: To reduce the percieved troll factor.
Someone who trades in their system and takes a big hit in terms of cost just to play another game like MGS4 doesn't seem like they have a big attention span and I doubt that he'll apreciate the excessively long cutscenes in MGS4 especially without first knowing the backstory of the game so he can understand them.
Tease.
