I usually play casual games not with Arena mode like Terraforming Mars. But recently I encountered some issues of other players delaying the game much more often. All of my last 4 TM games ended up with unfinished ones like that. It's really annoying so I recommend some rules change.
I have to say the most favorable way to play a game with people all over the world is to choose the option of 4 moves per day (+6h every move). Under such circumstances, is it feasible to shorten the starting time limit from 24h to 6h? Many of the turn-based games would be delayed anyway, why don't we find it out as soon as the game get started? Currently for a 4-player game, the worst thing is that we have to wait for 24h*4 to find out the game should be abandoned, which is too time consuming.
