Here's a video I got recommended recently:
Not only does he have multiple copies of the "rare and expensive version" of Japanese Tetris, and not only does he have multiple BOXED copies of various "versions" (you'll see how slight the differences are in the video), this fully grown man gasps like a woman who just witnessed a car accident when he sees that there is a missing hyphen in a game manual/box.
That's it. That's the whole difference. He's excited about that. He has at least 10 copies of fucking Tetris.
