Well, that's the other issue. Don't want to have design by committee either. You can put a script together but you've got to know where to put your foot down.
I enjoy brainstorming but I've got waaaaay too many irons in the fire (again :sigh
with my art commissions
(not to mention bills I procrastinate on) Maybe something I could support in the future (to a degree) - if some other things work out, but not necessarily in the "short" term.
I would aim for something no longer than 10-15 minutes for the first draft - excepting atmospheric non-tf character development. PM me if you want to discuss stuff more by email/chat/etc.
