Check out this game. It's called CosmicBreak. It totally copies BoutCheetah.Not a lot,but it does.
www.cosmicbreak.comI realize the innappropriate content but really,just take a look.
Quick Description:CB is a type of MMO where you fight the Chaos in a Cyberspace World. You start out by choosing a certain class:Air,Land, or Artillery. Once you've chosen, you go through training. Once training has done,you can choose a "guild". The three guilds are Dostrex for Strength, Wisdom for Smartness, and Bladine for Courage/Balanced. Once done with all this, level up and keep fighting to save Chaos. There are 3 modes to fight in:Quest,Mission,and PvP Arena. GMs are constantly updating CB and have developed a new game called CC,Cosmic Commander. End of Description.
So it's kind of like BoutCheetah, where you go continues play, fight in 3 modes, etc.
