I'm slowly building a collection, I focus on the good stuff that nobody wants, like PS1 and Xbox racing game as a good example while some are a pain in the butt to play, they will keep me busy for probably the rest of my life. However most things like Super Nintendo games and Most GameCube games I'll probably never own, because as Long as I've been a collecting, they are too high in price and they are not enjoyable to me.
I think I don't I even own but 10 Super Nintendo Cartridges. Super Nintendo games are all probably put away in everyone's collection or in some scalpers storage bin, except my own. and I don't care because at least most of the stuff I want is affordable.
The SNES Mini/Classic is all anyone needs in my opinion, there you got Super Mario World, Starfox and Starfox 2, Super Mario Kart, and all most of the other $50 USD and more games included on it.
