Uh, its called opinion, budge.
If he didn't think MGS4 was worth mentioning, then thats his deal. Even though he hasn't played it, that doesn't make his opinion invalid if he says ''I don't know, that ridiculously over the top story business is just not for me.''

I do have a PS3, princess, I just never get online with it since the only online game I have is Warhawk (got boring after a while), and UT3 (rather play the 360 version). I think my user name is 'tiredforawhile' though. For some reason I have all sorts of trouble trying to get into online matches with it. Shit'll sit there forever and I'll just get errors, so I just gave up and use it for blu-rays/single player goodness.
