CitiesXL was forced to make a difficult decision. An email was sent out to all players this morning informing them that as of March 8th, Monte Cristo will be putting an end to the Planet Offer: "Three months after the launch we have to admit that the subscription rate is lower than what we expected and therefore the Planet Offer is not sustainable. Not enough players decided to subscribe."
The CitiesXL team has our sympathy -- it's never easy to make such a decision -- but there is a silver lining. While players can no longer visit other cities, trade tokens, and so on, CitiesXL will continue to exist as a single player game.
Monte Cristo has also added an FAQ to their official site, and the complete letter to subscribers can be found below, just after the jump. Presumably, this will be the last time you'll hear about CitiesXL on Massively, so we wish them the best of luck on the single-player version.
