Card games !!
I've always played some kind of card game for most of my life. As a little kid, it was Pokemon. As a stupid kid, it was Magic: The Gathering, and as a stupid adult, it's Pokemon again.
Somewhere in the middle of those was some Bakugan (original) and a tiny bit of Yu-Gi-Oh! via Master Duel, but like, who's counting?
Don't let me get started on BattleCON I will praise that game until the end of time ~
