List of dead 1 button fighting games that no one actually likes and casuals don't support:

Fantasy Strike
DNF Duel (Motions are even more useless than Granpoo lol)
Power Rangers BFTG
Blade Strangers
Divekick
Footsies
Basically every Smash clone (Nick All Stars, et al)
Probably some other random indie games I'm forgetting

Soon to be 2xko if it ever comes out

It was a failed experiment, let's just pack it up and make fighting games for the people that actually play them.
