Ive often thought about an Emancipation Proclamation Wonder, or the Communist Manifesto, but I was wondering if it was possible to implement the effects I desired. The EP would turn all enemy Civ slaves into (good) barb units, or they would turn into 'good' workers for the builder Civ. The Manifesto would cause all other Civs to fall into Anarchy, essentially wasting all construction for 4 turns (apart from Religious Civs). The Manifesto should also stop worker production in the enemy Civs. It would be a GA trigger for Industrious Civs too. What do people think?
