Okay first my apologies to the player that I (from many miles away) soundly cursed yesterday, it appears he timed out or forfeited and then the game sat doing nothing at my end....and I had actually won (score and rating went up)
But aside from that I have had the occasional player sit on turns, to try and bore me to death in the later stages of a game..... anyway all's well
There are reasonable time limits at the moment:
60second idle timeout (if you idle 60s you lose),
4minute total turn length (end turn will automatically follow).
In my knowledge, so far there has been only 1 thread in the forums complaining about deliberately slow player.
And I must say thank god it wasn't about me, because I hate making stupid mistakes and I tend to take my time when playing seriously.
But naturally, especially when starting Cabals the rounds may take a bit longer time because there's so much to digest.
