NES, SNES, PS1, even modern indie games designed in the old school 8-bit or 16-bit aesthetic. I have a console called the Retron5 that has cartridge slots for NES, SNES, Sega, Game Boy, and GBA, it outputs everything in glorious full HD and has a variety of display filters. I've never had as much fun with modern big budget games as I used to playing 2-player co-op games liked Double Dragon on Super Nintendo or classic RPGs games like Chrono Trigger and Final Fantasy VII.
I'm also a collector of Nerf guns. They're way cooler today than they were in the 90s, now they're magazine loaded or have 5 to 10 round revolver mechanisms. Nerf fights are insane fun and the hobby costs practically nothing compared to electronics and car stuff. $20 for a big gun, $10 for a small one, and extra darts are dirt cheap.
