Glider posted RevolutionMP beta version that we should be able to use with RoM 2.71. Check his post about it here. What should work: 1) All Revolution game options like barbarian civ etc should work in multiplayer 2) Single player should work as per normal all options ok (Just return Revolution.ini to default) What will not work: 1) If a player dies in multiplayer, game will OOS. I guess in this case, the multiplayer autosave could be reloaded by the host and play continued. This problem could have serious implications for AI's that die as well. Not sure. 2) If a player selects "defect and lead rebels" in multiplayer, game will OOS 3) If a player selects "accept and take control of new civ" in multiplayer, game will OOS 4) "Handover control" Revolution option has been disabled in multiplayer mode only The reasons why options 1-4 above do not work is because currently the change player and auto play mechanisms do not work in multiplayer and cause OOS.
