WHAT IS MUGEN ?
Mugen is a free 2D fighting game engine. It allows you to make your own fighting game (with your own characters, backgrounds...) Mugen is very configurable and powerfull and he has a very good gameplay (I think he'a as good as a real KOF or Street Fighter Alpha 3). The only true defect of Mugen is that it's difficult to make a character. But the more difficult is to begin, after some work it becomes more and more easy, and you'll love it :) ... But if you don't have time to make your own character, you can always download characters made by other people.
