Oh hell yeah. The 151 original, Japanese version, holographic versions, rare ones for events, etc. Still remember how excited everyone was to get a pack even though no one knew how to play the actual card game. Just don't take them to school because if you're caught with them outside recess you'd never see them again.
The Gameboy games were the absolute shit, too. Only played the first two generations and their remakes but all the hours spent on the Gameboy playing them were good times. Still have all of them and may need to boot it up at some point.
