My group tends to over-analyse during combat, which slows everything down.
I press upon my players to make their decision and roll the dice quickly. My players are all experienced in the system and I rarely provide a description that is inadequate to make their decisions. I get the odd question, but it usually precedes something daring outside of the system - which is fine by me.
If a player takes too long, I skip their turn - assuming the character is doing something 'sensible' but not taking positive action. This is understood by all as the way it is in our group. As far as I know they find this way fun but we have a polite group that would roll with the punches.
However, is it fair to force the players the make decisions quickly in this way? Is putting pressure on them a reasonable request?
