Snatched from Wikipedia:
I'm surprised a thread for this didn't exist already, especially with the upcoming release of DotA 2.Defense of the Ancients (commonly known as DotA) is a custom scenario for the real-time strategy video game Warcraft III: Reign of Chaos and its expansion, Warcraft III: The Frozen Throne, based on the "Aeon of Strife" map for StarCraft.
Been an active player since 2007, which is unusual; video games rarely hold my interest for long. DotA has insane replay value.
Who else plays?
