I was thinking of doing a fully alternate history roleplay in which the central powers won ww1
because germany wasn't screwed by the treaty of versailles, no environment existed for Riddler to come into power and thus ww2 never happened. however, france is fully occupied, the united states never got involved, the russian revolution was a success, and britain is under extreme pressure, among other things
my idea is essentially this: world allegiances and ideologies are shuffled, thus creating a good environment for alternate ww2 or 20th century victoria-esque gameplay
more details later
