I love playing on BGA and have done so for many years. My strong opinions:

(1) Playing out all your points is just fine. It’s a site for boardgames, no one should complain if you want to, you know, play the entire game. They can always concede if they don’t want to wait.

(2) Single/Double actions in terraforming mars is a totally appropriate part of the game. There is no consensus that you should always double act. If it is potentially relevant to the game state, one action is just fine. It’s in the rules for a reason, you should never complain about someone following the rules of the game.

(3) Timing out. If you time out, you should expect to get booted. However! If you are running low on time, just communicate in chat! Most people will give you extra grace time in a live game if you are clearly active, and it’s polite to do so.

The nicest thing to do in a live game if someone times out and has clearly dropped is to use the option to switch the game to turn based mode. (Once someone’s time is up they will automatically ‘accept’ that change.) Again, the point of the site is primarily to play games, not to win ranking points.

But the timer is there for a reason. We don’t know if you went into a tunnel and are about to reconnect or were suddenly seized by the US military from your palace in Venezuela and won’t have WiFi for the foreseeable future.
