We are open for discussion and think tanking. We already have our premise and story outlined in a GDD but I'd be happy to help too!
The fact I had to look up what GDD is shows me how far I have to go... :`(
Naw. I'm just old school. Everyone has their own process and way of doing things. If you write anything down at all, for story, planning, or aspects etc... , It's a GDD basically.
