I'm curious about what games have turns that become longer as the game progresses. For example, at the beginning, you may not have much you can do with each turn, but as you gather resources, build, expand, or somehow increase your options of what you can do on a turn, then it takes longer to take your actions, etc.
Now as you have more to do on your turn, it's going to take longer. That also means more down time for the other players as they await their turn.
So what games have turn length that grows as the game progresses? How do they keep players from getting bored waiting? What kind of interaction exists - trading? Interference?
Are there other ways to keep players involved or engrossed when it's not their turn, such as in Scythe, where players can start a turn while the previous player finishes theirs?
My game in particular has growing turn length, but there is a good amount of player interaction available, so I don't feel it's too much of an issue. However, it does limit the # of players. Originally I wanted 5 or 6 players, but that would make a pretty long game, with a lot of time between turns in the late game. So I dropped it to 2-4 players.
I'm just curious if there are games that have good ways of dealing with turn length - either helping players to make decisions more quickly, or things they can prepare for their next turn, etc.
I think I have enough player interaction, so I'm just exploring what other things might help.
