One of the biggest costs for maintaining the game was moderating the game's community by making sure that there were no obscene Lego models created by players. This meant that every single player created in-game Lego model had to be looked at and catalogued to make sure that it was age appropriate, I.E. no penises. This was to help make sure that the Lego brand remained family friendly.

One developer was almost fired when his in-game built Lego penis was discovered by a child tester during a "kid test".
