My gaming group is very mature, empathetic and thoughtful; in character and out. They are pretty much the perfect gaming group, but one of the players whose opinion I trust to be honest has come to me with a complaint that I think more of the players would voice if they were more honest in their criticism: the group takes to long to come up with and enact plans which causes the game to drag and lose momentum and direction. I know the players, even the one making the complaint, enjoy planning to a certain degree and I don't want to take that from them, but I want to be sure we can make the planning portion of our session fast, engaging and fun.
In our V20 game last night the planning took up 2/3 of the session and resulted in very little appreciable change.
As the GM I feel that it's my responsibility to keep the game moving at a brisk pace especially since we are only able to get together for 3-4 hours a week. I prefer to run sandbox style games and I put a premium on player agency, that said I am willing to step out of my comfort zone to make my session as interesting and fast paced as my players desire.
The player also told me that while she wants the game to move faster she doesn't want the game to cause anyone anxiety either.
In what ways could I change the way I GM or ask more of the players to make planning go faster and be more fruitful, more fun and interesting for everyone?
