I am currently playing Hot Seat Civilization with my brother but we didn't find a way to play a scenario or a world builder save together.. only the randomly generated maps.

Is there a way to play for example the Earth Scenario in Tcp Multiplayer or Hot Seat?

Any kind of help would be great.

Sorry for you - but right now it is not possible to play custom maps or scenarios in hotseat or PBEM.

TCP should not be a problem - but I don't know for sure (the only MP mode I play is Hotseat...).

I guess they will sell us an expansion pack in a few months with further MP support (like PTW...).
