For our recent contest, we challenged artists and designers to dream up the ultimate Blizzard Entertainment theme park, complete with the wildest rides and most inventive attractions they could conceive. Big congrats go out to Christina Marie DeLong for her detailed, grand-prize-winning depiction of Blizzard World, featuring such attractions as a terran combat simulator, a Diablo-themed petting zoo, and a thrilling flight around Outland's Netherwing Ledge. Congratulations to our other prize winners too, for designing the best individual StarCraft, Warcraft, or Diablo-themed rides or areas. Check out the winning parks below, along with several creative honorable mentions -- and thanks to everyone who entered!
