So I was planning the first session of my campaign. Almost got a date set, suddenly players say that they can't make it because someone else thinks their stuff has priority (this is within the roleplay association) and those people say that I have to plan for another date. WHEN I WAS FIRST!
Oh, and somehow, I got the worst people to plan for, so this feels even worse than normal.
That feeling of: well, finally, and then someone grabs a slabhammer and breaks it in thousands of pieces.
I am adamant about not having missable quests, which means having to write entirely new scenes at each plot progression that takes into account that time and events have passed since the quest could first be accepted while still having there be a quest to solve in the first place. It's worth every second.
