Sandbox virtual worlds are becoming the newest thing these days following the success of Second Life and the anticipated success of Metaplace, but VastPark has recently announced a partnership with a few companies that will serve to improve their spot among the ranks. First there was the agreement they signed with NICTA, Australia's Information and Communications Technology Research Center, and now they've formed a relationship with TurboSquid to access their catalog of over 195,000 3D models. This combined with the announcement that they'll be running their virtual economy through Twofish's economic Element engine.What's this mean for the players? It means a much more flexible economic system where you are in control of your own currencies, the value of your goods and the management of your markets. This basically means that each player-created world will have it's own economy. VastPark founder and CEO Bruce Joy explained, "This is a new step in bringing economic power to the masses. We also see it as a fundamental way for us to build value in our platform, as it allows for the creation of realistic, responsive and highly customizable virtual worlds."
