Really? From what I know in simul turns it is a random draw the game makes to decide who gets it, same for all wonders, religions, liberialism etc. So if 2 candidates 50-50 chance.
No, in warlords it was originally overflow, then it got changed to team number in 2.08 (there was a CCC future event semi final between RaY and MDR or LKT, where RaY lost when both launched the SS on the same turn, because RaY were team 2, even though RaY had the higher score). I think it got changed back after that, not sure though.
It is one of the downsides of a turn based game such as CIV, where be closer to the front of the team order has no downside (as opposed to poker).
