It's a common problem to wait for players during starting turn. So the good idea, I think, is to except making a time for normal turns, make an option to set another amount of time for starting turn, which shouldn't be shorter than the normal one. For example 12 minutes for starting turn, when it's 4 minutes for normal one, then it won't be needed to always talk about booting or not. Starting turn ended and it was much longer, so just boot (manually of course) those who didn't come and play.

I agree with this idea.. I think i said something once about a mandatory doubling of first turn/placement but don't remember...

I would post it on uservoice, but never figured out how to do it.

Don't understand the reasons for booting anyone on the first turn.

5L You dont understand but people don't want to wait forever. Some boot just if a player do not move in normal time of first turn, but sometimes the first turn is just too short. So it would be good that the first/starting move could be longer, and possible to specify by a person who create the game. But it shouldn't be shorter than normal turn as then it could be a way to cheat - somebody would make a round of 10 minutes, but the first one would be 1 minute and he would just boot people.
