I seem to remember in the old PS2 version, you could make the health bars go up to 400 points of damage. I very much enjoyed that because it allowed me to have long matches.
In Final Showdown, the health bar only goes up to 260. I really hate that. It makes the matches seem very short and very quick, forcing you to perform the quickest knockout combos.
I know that they want the leaderboards to be somewhat equal, but there should be an option to change the health bar more, and have your match NOT counted towards the learderboards.
