Okay, sorry for being so passive on this matter. Glad you guys are excited!
Here's my proposition:
We do first a "quick" test game.
We team up people in teams of 2, with one player more experienced, so that he or she may be able to instruct and give hints to the other half during the game.
We also insert AI players in the game in teams of 2.
Map type: Continents (semi-safe, more focused on interacting with people in the same island)
Map size according to how many people are willing to dedicate to the game.
Speed: Quick (I personally prefer marathon games in Civ, but I consider this infeasible in such a multiplayer game)
Difficulty: This can be adjusted personally. I would suggest, that experienced one in the team takes King difficulty, while the newer player taking Chieftain difficulty. These difficulty levels will mostly change percentage based bonuses during the game.
All victory conditions available
You may choose any civilization you wish.
We include Gods n' Kings if everybody has it, leave it out if at least 1 interested CCGR'er doesn't have it. No other DLCs or mods.
I would prefer us to set a day that we try to play a game every week or every other week. All participants would be ready to play 1 or 2 hours in the set dates, after which we agree on when to stop, save and continue later on. I am euro zone (GMT + 2, EST +7 I believe).
If somebody can't make it while everybody else is present, or wishes to leave in middle of the game, acknowledge that an AI will replace the player and continue the game. Therefore things may be messed up the next time you actually take control again. Alternatively we may try this multiplayer bot thingie you guys posted, but I think set dates may work rather well (?).
I think with this setup we could finish a game in several weeks. This is just my wild guess though.
How about Saturdays EST 4 pm / GMT 9 pm
/ 11 pm my time? Leaves me nice couple hours to play before still comfortably going to bed. We could maybe start next weekend
