Defense of the Ancients

Defense of the Ancients, created by a mapmaker known as "Eul", was inspired by a Starcraft map named "Aeons of Strife". Eul did not continue updating his map after the Warcraft III expansion The Frozen Throne, so many variants were created. The most popular variant is DotA All-Stars, first developed by Steve "Guinsoo" Feak and Steve "Pendragon" Mescon until the release of version 6.01, when Icefrog continued development.
