Then, you pretty much don't like Metal Gear. You just enjoy the gameplay and maybe the interactions that some characters have here and there.
Is not a sin not liking MGS3 but it is kinda weird. Also you can always skip those parts in the game so is not really a big problem.
Anyway, I wasn't really interested in buying this collection other than for Peace Walker but goddamn that artbook that comes with the limited edition is pretty sweet. I didn't expect that the artbook was going to be that huge, too bad that I just have money to buy a $20 PSN card... ah well, you win and you lose in life. Maybe for the next anniversary I'll have money to buy whatever the hell they do by then.
