A big drawback of the incremental model is that they require peeps to keep playing to stay fiscally sound. This didn't happen here, as I'm a typical gamer, and it folded. Even if players leave on normal funded model games, or like me, buy the thing and don't get around to installing it for a year, it's still reached its funded goal ( or not ). Eitherway, the expenses ended and the rest is income.
Overall, CivWorld was just an unfun, must multiplay ( not single player friendly ) game. That latter overlook really killed it. If there was a challenge singly, I would have played more. Also, if it wasn't for Dan's 'Cast advertisements I would have forgotten about this civ version several times. Extremely poor advertising.
