I’m ecstatic this is happening! I thought that a fighting game framework was way beyond the scope of anything Epic was in a position to provide as sample content.
A word of caution, please take great care when interacting with the competitive fighting game scene. They are…opinionated, and they assume they know a lot more about the technical details of game engines than they really do. Be prepared for them treating every feature you add as a confrontational endorsement of every game that used it.
Anyway I thought it was worth suggesting to everyone this really excellent talk on procedural animation by David Rosen (Wolfire). Fighting games need a huge amount of animation content just for basic gameplay to function. Being able to prototype and balance movesets rapidly based on just a handful of keyframes seems like a godsend for indie devs.
