I didn't seem to have any problem creating global quest scripts in Oblivion or FO3, but I can't find where to set up the quest in the NV GECK. Do you set up quests in the tree or is it from one of the menus (specifically where)? Thanks.
i hope i understand what you're asking properly!
open actor data then click quests, in the quests list right click > new
then the entire quest editing window should open
hope this helps
