Valve owns a copyright on DOTA so there's more than that going on. As for Blizzard owning DotA, HoN came out already and its almost an exact ripoff of DotA and that games still selling.Dendio said:Doesnt blizzard own the rights to dota in some form?
It was created through their own warcraft 3 video game after all
Anyways, if blizzard was that hung up about making all styles of games invented by them their own, Tower Defense maps wouldn't exist outside of blizzard. And yet...
Oh, as for how they're making heroes, I played an AoS (aeon of strife, the game DotA was based on from SC1) on battle.net and they were able to make heroes with skills--but there were no attack projectiles.
