One of my players recently told me that, although she's enjoying the game, she feels a bit like a passenger - that she reacts to stuff, rather than ever making decisions. She accepts that part of this is because she's never really taken the time to flesh out her character (so, in her own words, her character is "plot-driven" rather than "character-driven"), and also is aware that it's partly because her character is quite a quiet, sneaky sort of dug, who isn't instinctively at the forefront of what the party decides to do.
I'm talking to her to see if we can find ways for her to feel more involved in the decision-making, but I just wondered if other GMs out there had had similar issues, and (if so) how did you address them?
Thanks in advance.
