When I was younger, a good friend gave this game to me. It ended up becoming one of my most played games. Loved the character designs, stages, and the way it played. Ring outs was another feature I was fascinated with in those times.
The series has an interesting history. Started out as a PS1 exclusive dubbed the "Saturn Killer", only to end up on the Saturn shortly after.
Earthworm Jim was in the PC version of the game.
Interestingly enough, Capcom published the Arcade version of Battle Arena Toshinden 2.
Most of my experience is based on the 1st game. I played 2 and 3, but I didn't invest any real time into them. The 4th game felt like a game from a completely different series.
I wouldn't mind seeing this rereleased down the line, though I know it seems unlikely.
