The original Mario War was created by Samuele Poletto in 2002, in which four Super Mario characters could fight on various levels by jumping on each other's head. It was written in Pascal/Assembly, and was released for DOS. Later versions also included a map editor. In 2004, Florian Hufsky, founder of the 72dpiarmy forum started working on an open-source rewrite, which became Super Mario War. This version introduced custom characters, additional gameplay modes and map mechanics, items and powerups. Custom user contents were stored on (the now defunct) smwstuff.com site, with thousands of maps and skins available. Due to its open-source nature, the game has been ported to pretty much every desktop and console system.
