The world of Colonial Gothic using the True20 system instead of it's normal house system. Typically when a product is converted to a "generic" system some of the style and feel is lost. Though I will say that CG survived with much more of it's soul intact. The system is normally a very easy one to learn so the conversion here does not sacrifice complexity. The game is still same, one of a supernatural New World as it becomes a new country, America.
The conversion does highlight many of the pluses of the game including it's atmosphere and style of play. It also allows you know to bring other True20 that might be helpful. In some ways I prefer this to the original.
