I know shit-ass nothing about POP figures but have you ever looked at the CWCki article that lists Chris's game purchases? Before the fire he had loads of physical copies of games for consoles he didn't even own, for reasons that Chris himself is probably not even sure of. He's extremely prone to spending frivolously on collectible shite that does nothing, just because it's available at the time.
I'm aware - he also went so far as to buy DLC for games he didn't own physically or digitally.
Chris buys with money he doesn't have because in a way, that's how his formative years were spent. IIRC the story is that to try and make Chris speak, Barb would take him to the store and if he could read the name of a Transformer, she bought it for him.
And, really, besides food, gas, bills, and the occasional fine, Chris really doesn't know what to DO with money. His life is truly so empty that buying more and more genuinely is the only thing he can do to get a buzz. It's one of the few things he lives for, given as much as Sonichu/CWCville is an escapist fantasy, even Chris seems to have gotten the fact it isn't a true replacement for reality.
Honestly he's at the point where he is essentially trying to find purpose in his life and unfortunately the way his life turned out, he genuinely does not have one
nor really the means to find permanence in them. That's why Bronycon was so monumental - he could be as weird as he wanted and still socially accepted. He would live at Bronycon forever if he could.
That's a different room, in his Captain's logs, he used to always announce it as "the work room, which is separate from the bedroom!", which I always found weirdly funny, like he really wanted to let us know that he's a grown-up now, so his bedroom isn't filled with toys like it was before.
Funny how that bedroom is SLOWLY gaining toys and other shit as well.
