At BlizzCon 2009, Blizzard's executive vice president of game design Rob Pardo revealed plans to allow modders to sell premium StarCraft II maps via the Battle.net service.
Blizzard wants to foster the best mod community in existence. They've unveiled plans to single out premium custom-created maps for sales on a StarCraft II marketplace. Maps will be split into two categories—normal and premium—with the former free and the latter for sale, with a portion of the proceeds going to the map's creators. Blizzard hopes this will lead to more choice for StarCraft II players, and more innovative and creative custom maps fuelled by the potential financial rewards.
Said Pardo, "This is really an opportunity for them to share in the rewards of our success."
The feature won't be available at the game's launch, and details are still being ironed out. Blizzard made the announcement today as a way to give modders time to gather teams together and start brainstorming premium content. Mod teams, start your engines!
