EZ-Fighters looks fun as well.
Don't know the link though.
Tried Kwonho, didn't like it.
BTW:
Will they ever make a online game that plays exactly like Power Stone or War of the Monsters?
War of the Monsters was a very innovative fighting game. It was one-on-one, but you were roaming around a city like a third-person shooter.
Power Stone was a good game as well.
