I have a PC who is a great roleplayer, but is also usually the only one making decisions for the party. In combat and in dungeon crawls this isn't really a problem as the goals or next hurdle are rather linear. However, in the last session the party spent some time roaming free in the local town, and this player got a little peeved at how the other players did not submit ideas for 'where to go next' or 'what the plan is'. Then the player just stopped providing ideas for what to do next and let the other players flounder until I moved the story along on my own. I'm sure this varies group to group, but how do you encourage all your players to provide ideas to the party? Drown your players in adventure hooks so there are always plenty of options?
