Currently mine is for the PS3. I'm over 120 (physical) and I'm still going. It should be close to 200 by next year since I'll be still collecting even after I get my PS4.
Second is my PS2 with over 100
Third my Gamecube with around 55 or so.
Hahdheld would be Vita with around 10 or so. I'm not big on handheld gaming, but this gen has two great systems, so I'll likely have over 20 for both by next year.
How about you? Anybody with the Ouya at numero uno!?!?!! LOL! (joke, of course).
Playstation = The Beast from the East
Sony + Nintendo = WIN! PS3 + PSV + PS4 + Wii U + 3DS
