Central Powers: GreyLord House Rules is a variant of the Table Tactics game, Central Powers. The Central Powers A&A variant doesn't really do much to replicate WWI, all it does is add some pieces that look like WWI pieces, and add them to the board. THIS HAS NOT BEEN BALANCED in the least. All it does is add some more flavor. As such, it is a work in progress that anyone is allowed to add it with changes.
