Winning on the Same Turn

I was playing as the Romans, going for a cultural win . Saladin was building the world bank as i was building the united nations. We finished on the same turn, and it gave me the win.

Anyway, the purpose of this was 1. How do wins on the same turn work in multiplayer? 2. Do you think it is overpowered that the Romans half price wonders ability includes the winning wonders(World Bank and United Nations) Cause i do, even though it was the reason I won.

It might go into a tie breaker like who ended there turn first or something, wow that is a good question you should email them to find out and post it here, I'm sure it doesn't happen very often and the odds of one of the few people who it has happened to being here are low so that is probably the only way we'll find out.

It could be the person with the least hammers left to build the wonder will win. I belive this happens in Civ 4 when two civ each finish a wonder the same turn. Otherwise, I'd guess it would be random.
