RPG

I use the superior method, a mess of illegible scribblings in a journal. I am trying to get better about it, though. And one thing im really trying to do is focus my prep on what the region is like, and what the important actors there are doing, and not on what i think the players will do. Every time I try to predict the pc actions they completely flip my prep on its head, so I want to go for more of an "informed improv" type prep

I use Onenote, it's free. Let's you have a book with folders and pages. You can have blank lines dotted or graph paper. You can use it to search images uploaded to it. Combined with a surface pro to write on the screen I can do everything I want to from draw maps, edit character sheets and take notes. You can hyperlink between pages and print pdf's into it. Fabulous piece of software for RPGs.

Obsidian! Can't recomment it enough! It's simple, has everything I need and a shitton of plugins (dice roller, statblocks, Initiative tracker, fantasy calendar, a tool for working with maps with pins and everything, ability to embed all sorts of generators from generators websites, wiki styled notes and more!)

Haphazard scrawls on a notepad during the session, trying to not lose it in between the initiative orders and scribbled HP tracking from combats. After the session I try to collate it all into a OneNote where it's all organised by campaign and plot element and theme.

Lately I've been moving from OneNote to Obsidian. Obsidian's ability to link between files and then see the visual map of all the links is handy, and it can even detect mentions of a thing even if you didn't link it at the time, so if something becomes important enough that you later decide to create an actual page for it, it'll find all the places you previously mentioned it. Very useful.

Poorly! I do it poorly! :D

Characters are in GURPS Character Sheet, an (awesome!) open source character management program. I run our games through Foundry VTT, which handles all the combat tracking, HP/FP management, maps when I have them, etc. It also imports GCS files (and GCA, if that's your flavor of character editor). Most of my other notes (events, generated people names for unexpected NPCs, etc) go in Google Keep notes. Notes that I have to take on the fly go into my notebook, where they go forgotten until the next session, more often than I'd like...

Between sessions: Google Docs (one document per campaign)

During the session: I'll print out the document and scribble on it with a pen as needed. I've tried editing the doc live (via laptop) during the game but it takes too long and requires too much focus to type as opposed to just jotting down/crossing out as we play.

Obsidian is a personal favorite.

@jursed I use Google Docs for just about everything. That way, I can call them up on any of my devices whenever I need them.

I use obsidian, and git to sync between devices.

I'm a big fan of the Notion template from Sly Flourish. You can find it here: https://slyflourish.com/lazy_dnd_with_notion.html
