Between me and the boyfriend we have...NES, SNES, N64, gamecube, Wii, WiiU, gameboy color, gameboy advance, DS lite, 3DS (x2), PS3, PSP, Xbox, Xbox360 (x3), Xbox one (x2).
We game a lot together so that's why we have so many multiples. There's also two nice gaming pcs in our house and a lot of accessories for everything.
I'm just about to dust off my WiiU since I picked up Yoshi's Wolly World this morning.
