Mike Zaimont covers a lot about how he believes fighting games should be built and developed for the user experience. He covers topics such as using rollback netcode (GGPO specifically), providing hitbox data to players, as well as frame data. I liked this talk as an example of providing information you as a developer have to your players if they so wish to use it.

There is some significant overlap with fighting games and beat ’em ups when it comes to general combat in any 2D platforming game, so it made sense to look to these sources for more inspiration and options for designing a combat system within such a game. Using a fighting game frame system with start up, active, and recovery frames can also be tailored to work with general combat systems, so when looking to be flexible it makes sense to use a system like this that is applicable to many cases.
Neither of these examples specifically get into a specifically frame driven system, but they at least show the basics of tying animations into actions and hitboxes more, as well as exploring combos and possibly input buffering more as well. These options at least help expand some of the more basic combat options I have seen in more platforming focused 2D sources.
