The game, called Ellark, will be a free-to-play title with a microtransaction payment model. The company is planning an entire currency around this concept, calling it a MobiCoin service. There aren't many good English language descriptions of their plans, but MobiCoin is a concept that's been tossed around for some time. There isn't much to discuss as far as gameplay goes, but the service will apparently make use of text messaging for communication between players. The release calls Ellark a "Mail Play Game", which has some interesting possible permutations.
