What part of campaign prep eats the most of your time, and what have you tried to fix it?
I've been running games for a while, and prep keeps taking way longer than I expect. I'll sit down to plan one session and two hours later I'm still naming NPCs and trying to remember what I said about a town three sessions ago.
I'm curious how other DMs handle it:
Which part of prep takes you the longest? (worldbuilding, NPCs, encounter balancing, session notes, tracking plot threads, maps, something else)
What do you use right now? (notebook, Google Docs, Obsidian, World Anvil, LegendKeeper, Kanka, AI tools, nothing)
What bugs you about those tools? What made you stop using one?
If one thing could disappear from your prep, what would it be?
Most of all I'd like to hear from newer DMs who feel overwhelmed. What made your first campaign hard to get off the ground?
