Even though this has devolved (as most long running threads tend to do) into a not very interesting minor flame war, I'm going to toss in a pertinant piece.
Many independant RPG's are at present exploring systems which increase player control and participation, while decreasing GM power. (They also tend to be "lets pretend" type things, with very light stats). I think its important to give some of these a try, simply to broaden one's gaming horizons.
Some samples (none of which I've played - yet) are Prime Time adventures, Polaris, THE SHAB AL-HIRI ROACH, Mountain Witch, and others. We live in an interesting time, in terms of role playing game experimentation. Both the Roach, and Polaris don't even have game masters.
