I think I should have known that I was a weeb all along for being obsessed with Metal Gear Solid 1-3.
This is an almost reasonable assumption, but unfounded. Plenty of dumbasses out there obsessed with Kojima's ham-handed, derivative, self-indulgent storytelling. But just because he's Japanese doesn't make you a weeaboo.
Go read a couple Tim Rogers "games journalism" articles, and see if you enjoy those. If so, you may just be fascinated with narcissists.
