Hmmm.... tough choices, and I may not interpret them the same as anyone else, but given those particular choices I voted:
- Absolute power over houserules, genre choices etc but only in advance.
- Final say on scheduling.
Everything else ends up as entirely group consensus. (I'm not sure where the mutually exclusive choices begin and end, so I voted on those 2 options, above.)
However, for our particular group, I'd yank out "houserules" from the above, and move that one to the "primary but not absolute" choice, since that was an inappropriate lumping together AFAIC, but that's the way it goes with internet polls, I suppose.
Further for our particular group, the DM (me) also happens to have:
- Final say on group membership, and
- Final say on social aspects (table rules, eating, smoking, etc);
... but that's only because it's at my house. For us, these two would be the host's role in game and group, not the DM's.
