Until about 2 years ago I had:
Nintendo Famicom (NES)
Sega Master System (Mark 2)
Sega Mega Drive (Model 1)
PS2 Slim
PS4 Launch Model
Wii
WiiU
Nintendo Switch
I only have my WiiU, Switch and PS4 left

The issue was actually keeping everything hooked up and composite video looks terrible on modern tvs, my last CRT gave up the ghost. I switched to emulation and it's not quite the same, but it scratches the itch. Also, I didn't have the time to give it the attention it deserves. Some days I miss them especially when watching Gamesack on youtube, but c'est la vie.
