At another site I was at, where the site was based on chess, you had a set amount of time to complete your turn when it arrived. Normally 3 days. They had a feature similar to what I am going to propose.
Here, the concept is the same, but it is always 24 hours since the previous player ended their turn.
I suggest that not only can turn lengths be decided in the "Create a Game" section, but also a Vacation feature be added. You can use up to 14 days a year for vacation, and while the vacation is active, games where it is your turn are held until you return. Or, at the very least, you are not kicked from a game for missing a turn.
I have lost 2 games where I clearly had the victory had I not been kicked. And I'm mad about it. But that's just me.
