Warcraft III: Reign of Chaos was first released in 2002, followed by its expansion pack, The Frozen Throne, in 2003. The game's popularity led to the creation of DotA (Defense of the Ancients), a custom map that added a new gameplay style to the game. DotA 1.26, in particular, is a popular version of the map that many gamers fondly remember. The map's complexity, balance, and competitive gameplay made it a staple of the gaming community.
