EA ActiBlizz Ubisoft - Horrible DRM, Uplay not recognizing some games or accounts. Sony - Strictly because of the shady EULA wording. Which included threats of disabling the console, if you disagreed. Yanked out the ethernet cable, almost two years ago. After reading the previous four.
Ubisoft. I just don't like any of their franchises. Nothing personal, but they're pretty much the only company lacking a franchise I'm interested in. I might buy a game or two for a kick, but I can do fine without.
SE and Capcom got too many franchises I don't want to abandon yet. I've loved the hell out of Street Fighter 4, my favorite fighting game ever, I enjoyed Resident Evil 5, I liked Final Fantasy XIII, XIII-2 even more, so I'm not giving them up despite a somewhat mediocre current gen. I've been a lifelong fan of both companies since the NES days.
