What is this subreddit?

Was scrolling through some moron’s profile who I was engaging in an argument with when I stumbled upon this page he’d posted on.

I have a Vita I bought brand new in Nov 2012, assassins creed liberation edition, which has really just been collecting dust for nearly a decade till recently a new friend i made offered me 300 bucks for it?? It seems they’re back in hype? Is this why he wanted it?
