I still use a paper notebook for games
There is a notebook on my desk with, at the moment, four maps of the same cave drawn at different zoom levels, a list of eleven lock combinations, and the sentence "the third door is the lie". It is not efficient. I keep doing it anyway.
A wiki answers the question faster. That is exactly the problem: the answer arrives before the question has had time to build. The part of a game I enjoy is the twenty minutes of being turned around in a corridor, and a search box deletes that.
What goes in the notebook
- Doors I could not open, with what I think is needed. Half of these are wrong, and that is fine.
- Routes through areas I keep getting lost in, drawn badly, with an arrow for "I came out here somehow".
- Things a character said that sounded like a hint. They usually are.
The real benefit
Writing a route down by hand forces me to decide what matters. A map on a second monitor has everything; a page has room for about eight things, so I choose the eight I actually need. I also remember them, because my hand wrote them, which is not a productivity argument so much as a fact about how I read.
The cost is that I cannot share it. If someone asks how to get past a certain area I have to describe it out loud, badly, from memory. That is a worse experience for them and a better one for me, and I have decided that is acceptable.
