It's more than that, apart from beeing DotA it's also HoN, which is a complete game, based very very very heavily on dota, down to the same items and heroes almost. It basicly took DotA and made it a stand alone game, to free itself of the problems caused by the WC3 engine.rabidmidget said:
I bought WC3 and WC3:TFT solely for DotA
