What I still own:
PS2
Xbox One S
Switch
og3DS (about to sell it)
What I have owned in the past:
Xbox 360s
Game boy advance sp
Ds lite
Wii
That might not be a lot of consoles, but that's because I've extensively played on my friends consoles throughout.
Bet with Intrinsic:
The Switch will outsell 3DS (based on VGchartz numbers), according to me, while Intrinsic thinks the opposite will hold true. One month avatar control for the loser's avatar.
