Hi,
In my opinion, if you get more than 4 or 5 humans in a game, the chance of completing it in less than 2 years is very small. Just 1 inconsistent player (i.e. someone who doesn't play their turn within 12 hours) can easily add a year or more to a game.
I'm in the same 2v2v2v2 game as Dazz. With 8 humans, we play less than 1 turn a week. It's very hard to get into a flow in a game like this.
Like Ruff, I enjoy playing with another human. In these games, you can strategize and learn from each other.
I would be interested in this game if we have 4 (or 5 or 6?) consistent players with either:
1. 4 or 5 players controlling 2 teamed civs each
2. 2 humans vs. 2 humans vs. (2 humans?) vs. 2 AI vs. 2 AI vs. ...
If the game gets more humans than that, it just takes too long, in my opinion.
I was able to get Ainwood to generate a map for our PBEM game with four players in the format of option 1 above. Each team has it's own continent (4 continents total) on a large map. As far as I know, since it's not possible / easy to enter World Builder in PBEM (thank God), we had Ainwood go in and do a few things:
Remove all huts since they add a huge element of chance to a game. One player may get Bronze Working while another gets barbs.
Ensure that each continent is a single solid land mass. I've seen continent games where one player is on a large land mass and his teammate is on a 4 or 5 tile island just off the coast. This wouldn't be fair.
Ensure that every player had a fair and approximately equal starting location. I generated a test map once and 1 civ had 3 golds, 6 flood plains, corn and a lot of trees. This player would get off to a very early lead and it would be hard to catch up.
By the way, I only have Vanilla, so if you guys decide to go with BtS, I'm out. I'm fine with whatever you guys decide to do. If you want to take this game a different direction with a lot of humans, I'll probably bow out.
