I can't see the map here while im at work, the firewall blocks it, but I will check it out tonight for team GP-Hawk to start discussing strategems. I have already sent an email for the good guys to start prepping for this game. It's a great idea, whoever came up with it, and I fully expect both sides, vets and "newbies" alike will learn a lot from this game! Just the fact that both players will be able to openly communicate all their secrets without worry about a backstab means a lot of information will be exchanged!
That being said, I think a big discussion point is tech trading.
Typically, multiplayer games have tech trading disabled, since it allows for teching agreements which means a couple players can team up and gang up on the "better players" and beat them with superior technology... which is sorta frowned upon unofficially.
But on the other hand, in a team game, obviously its in the best interests for a team to be able to openly share techs.
But on a third hand, its been my experience in a team game that the balance of the civ game itself gets messed up when you can effectively double your tech rate through the team, not to mention if 2 teams elect to have a master teching agreement for any period of time.
But on a fourth hand... what good is a team game if you can't share everything?
Its worth a debate at least, along with other settings that may normally be on/off that should be considered for a team game. How will it work with team-to-team interactions? Is this an "always war" type game, other than within the teams? What are our victory conditions? All of these things need to be considered to make proper civ selections.
