Ubisoft: 5 (no Just Dance, lol)
Warner Bros.: 2
Bandai Namco: 1
Square Enix: 1
I had some more third-party games in the past that I sold (1x Activision, 1x Capcom, 1x EA, 2x Sega, 2x Warner).
Way bigger percentage than my Wii and 3DS collections, but it will get smaller in the future due to the lack of support.
