IIRC, there was an option in the Gamecube version of CvS 2 EO to play 1v1. At the time I only knew how to play Chun Li, so I kept to 1v1. It is so satisfying, years later, to actually be able to use multiple characters and play 3v3 as the game intended, one of the characters being an SNK character no less (Mai)!
I do kinda wish they'd have gone with Alpha 3 Max instead of Upper, but I can't deny that Upper>>>>>>vanilla Alpha 3 that we got with the anniversary collection. And it lets you continue if you get beaten by Bison? This is madness... and I'm so here for it!
