Ive been buying essentially knock off games on eBay for $20 a pop and getting all the OG 64 games. I played 64 as a kid a TON, so it’s a blast for me. My collection is currently the original Mario party, Mario kart, Zelda, and smash brothers.
I don’t know anything about the switch though. I do like the idea of portability but we don’t travel enough for it to matter.
