JoJo's Bizarre Adventure: Heritage for the Future is, in my opinion, one of the most underrated fighting games I've ever played. The game has a lot of depth (though balancing is a MAJOR issue, see Petshop lol), with mechanics that are rewarding to learn, and the potential for really flashy and entertaining gameplay. Yet, it still remains very niche, and to my knowledge has never really broken into the mainstream FGC. This game is HELLA fun though, and I highly suggest checking it out and playing with friends.
