I am currently running a weekly mage game that has been going strong since May of 04. I have four players in the game, and only two of them seem really interested in pursuing the type of game I'm running. I have found myself tailoring the game to fit more their playing style and creating plot that they will enjoy more than trying to ensure that my other two players are having a good time as well. (Admittedly, some of this has to do with the fact that some of my players have been unable to attend game or, in some cases, have chosen not to attend game.)
For example, the two players who seem to really enjoy the plots I've been using have been focusing on a more character-driven, enigma based game. In last night's game, I gave clues entirely in haiku and the two players who have been regularly playing jumped in with both feet, and gleefully waded through the puzzles. The other player who was in attendance didn't really get involved in the plot, or only very peripherally.
Now, here's the question, since I've gone through all this build up: Do you find yourselves when DM/GM/STing creating plot and theme to match the most active of your players? How do you keep your other players interested and involved?
I've tried looking at this from a player perspective, and to be honest, I'm coming up blank. There have been few instances where I have not been able to make my character useful, even when thrust into the middle of situations where I would generally be out of my depth, and in those instances when I'm not being useful, I'm still enjoying the game and supporting the characters whose turn it is to shine.
Any suggestions? Comments? Screams of rage?
