How much FM does that get you?
I've done:
Story mode cleared with all characters.
Survival easy cleared with all characters.
Survival normal with all characters.
Some ranked matches.
Currently sitting at 417,850 fight money, with 26 hours on the clock according to Steam.
I don't plan on doing survival hard and hell with all characters though, so I'm hoping I can earn another 200k fight money by doing the stuff in the march update and completing that story mode they'll add in June. That would take care of all the season 1 characters, but there's also 1 or 2 alt story costumes I wanted to have. Although, as new characters get released, maybe they'll also get entries in existing story mode and survival so that I can earn fight money off of them too.
