I've never understood the whole, "I collect video games, I love collecting!"
"Wait, a second! Somebody has more games than me???"
"What a loser, what does he do for a living, look how much he spent! Terrible. I hate him. He's stupid!"
"Whatever, it's not that great, I'd rather have <insert random esoteric collection>."
That progression is a pretty clear-cut case, and a dictionary definition of the word "jealously". People have disposable income, if it wasn't sealed PS2 games, it would be modern art, motorcycles, or vintage lawn gnomes from the 18th century... who the hell cares. Collectors gonna collect.
