I saw and commented on another persons WoW collection not too long ago, and figured I might as well put up one of my collections.
So I more or less have every Metal Gear game that's been released within the US. I also have the Japanese collection on the far left there. I've kind of stopped since Peace Walker. I don't have the new HD Collection, and don't really intend to.
I don't know if I've just become disinterested, or am just growing out of it, but I don't have much of a desire to obsessively get everything as they're released as I used to. It might help that I just don't have as much money right now, and am no longer working. I'm also just about to graduate with my B.S. and am too busy stressing about getting my life started than to buy more games that I obviously have several copies of already.
