The battle for the Defense of the Ancients players has begun as developer Riot Games has officially launched their online multiplayer action-RTS game League of Legends. With a development team that includes some folks who worked on the popular Warcraft III mod it should be interesting to see how this stand alone game fares.

While the game is free to play, Riot Games is also selling a $29.99 Collector's Pack via download and in retail stores that adds some extra content including 20 of the game's Champions. However they have decided to give all players access to all 40 available Champions "for a limited time". In addition owners of the Collector's Pack will get a chance to get more of an experience boost than a normal player during this launch time period.
