This may sound crazy, but what this game needs now is some sort of google type ad system.
Throw in a small add while loading up a game from a creator. Be it a 10 sec ad spot or an unobtrusive ad banner.
Monetize the heck out f it with the main difference being that the same way users et money from viral youtube videos here they will get money from viral dreams creations. They do that and dreams becomes the game of the next decade.
