>>10265729>Fighting games like Street Fighter is the solid choiceFighting games in general have to have instantly cool and understandable character designs and are centered around action, so many of those games would be a good pick to branch into. Not just Street Fighter, they could look into Guilty Gear, Blazblue, Samurai Showdown, and have a slew of excellent designs.
Also, if they get some sort of broad-reaching license for Capcom, AY would become a de facto Marvel vs Capcom line and that's pretty cool. I think just about every Marvel character so far besides Moon Knight has been in MvC anyways.
