Project Entropia, an online multiplayer game, has begun hosting interactive ads, powered by in-game ad firm Massive Incorporated. The deal allows advertisers and brands to insert ad campaigns
dynamically into the game, which allows players to interact with one another in a virtual world, and features an economy based on Project Entropia Dollars, which operate at a fixed exchange rate to
the U.S. dollar. The virtual dollars can be purchased for real-world currency, and in-game assets can be sold for real-world dollars.
