Planet Calypso is one of the more interesting concepts in the free-to-play arena, as it's a game in which you can theoretically make real money from playing the game. It looks like the concept is expanding a bit with the announcement of Planet Arkadia, an environment for virtual treasure hunters. Part of the same overarching concept and universe as Planet Calypso, the game will be a chance for players to enjoy the thrill of treasure hunting without the actual logistical issues of stealing things and then selling them.

The game is going to bear another similarity to its predecessor, however, in that the treasures being unearthed will potentially be worth real-world currency. That should provide players of the game with a little added incentive, along with concept art by Feng Zhu and the promise of an immersive virtual world. Tentatively set for release in early 2011, Planet Arkadia already boasts a site with preview images and more information on the game environment. So if you've always wanted a chance for your virtual treasure to translate into real money, your dream might be closer to fruition than you think.
