I was also thinking a 24 hour turn game would be nice. Then I can just check in every day at the same time, no way I will find a good 12 hour routine for a few weeks. Probably would work if you just allocated more resources per turn with more initial resources. Regardless, looks fun.
Yep, planning on having some quicker games.
The best way to do it will be 5-10 min. turns with option to end your turn before that. If everyone is ready than it's not needed to wait and just jump to the next turn.
I recommend a game mode where you can check a box and send a notification to the server that you completed your turn. If all 50 players checked their turn then automatically update the server move on to next round.
