Current gen:All of 'em
Last gen:Just PS3, but got tons of Wii and PSP games.I'll also be getting XB360 games to use with XB1's BC.
Also got a PC which I use to play most multiplat games and to emulate the NES, SNES, N64, PS1, PS2, PSP, GC, Wii, and hopefully PS3, 3DS, and Wii U in a not too distant future.
Overall I identify myself as a PC gamer but I'm not sure of how true that is, since a lot of my gaming time goes into playing console games on PC LOL.
Edit: I also emulate GB and DS, but apparently not as much anymore since I even forgot to list them...
