i agree with Obex. dont change much just implement a lan/playbyip mode for the campaign map. all players making their turn after each other works good enough. and worked already good enough for similiar games (stratmap wise).

the time needed to finish an campaign is imo no real showstopper. anyone who played master of orion 2 or even more hearts of iron in mp will now that a good game can take a month or more to complete - at it deserves this high quality gaming time!

conclusion: i want a mp campaign for RTW!
