I was dreaming for a time now with a Dungeon Keeper multiplayer game! This is what I think, a good start :)
Although there is a lot of things to be made yet... First of all like many people said, we dont like to be forced to pay here on Kongregate. You devs should think about differents ways to get money that doesnt give some players advantage over anothers.
Keep it on with the game! But dont frustrate players that are not paying! :)
