A freeware game engine that allows you to play 2d fighting matches with an unlimited number of characters and stages. Infinitely customizable, mugen facilitates users' creativity and artistic skills as they create the various aspects of the game. First released in 1999 by Elecbyte, the community has thrived even in spite of the company's sudden dissolution in 2003. M.U.G.E.N. may be the best kept secret of the gaming community!
I collected over 2500 characters for M.U.G.E.N. in just three weeks!

A 2D fighting game engine, which can (in theory) be customized easily by adding new characters, backgrounds, sounds, and HUD elements (energy gauges and such).

The theory comes from the fact that the majority of M.U.G.E.N's character creators are whining bitches who lack any ability to share.

Apparently, taking a character and hosting it on your own site (known as warehousing) is an unimaginable wrong that you should be flogged for, even if you credit the character's 'creator'. Saving the 'creator's' bandwidth, and alleviating the need for people to spend hours wading through a million broken links and badly-designed sites in a multitude of languages is something that should never be done under any circumstances.

People often cite Elecbyte's discontinuing development of the software as the reason that the M.U.G.E.N community all but died. A little known fact is that the people who should have been the ones to keep it alive and fresh with new content actually killed most people's interest in the 'scene' by being possessive, whiny little bitches who decided that the best way to do justice to the concept of a nearly infinitely costomizable figting engine would be to do whatever they possibly could to stop new content from reaching people.
Man, M.U.G.E.N blows - infinitely customizable, and no-one wants to let people use the characters they stole.
