Has anyone tried out ObsidianMD for session prep or note taking? I'm trying to step away from Google drive.

I use obsidian for other notes i think it would be really good for prep and world building

If you want to go down this route, I may recommend cloning this Vault: https://github.com/Obsidian-TTRPG-Community/Pathfinder-2E-SRD-Markdown

It may not be fresh anymore (e.g. not remastered) but its still a great basis.

I'll have a look into it thank you! I saw someone (can't remember where) had their in game calendar and interactive map set up through obsidian. It seems pretty in depth!

I use Obsidian for everything! Highly recommend checking out this article from Sly Flourish https://slyflourish.com/obsidian.html

He does a weekly session prep video on YT where you can watch him prep his way using Obsidian.

I used obsidian for a little bit, but I just personally didn't vibe with it. It was over complicated for what I wanted and felt clunkier than I'd like. But for reference, I had been using one note which lets you put anything anywhere, and that's kinda my style.

That all being said, I am extremely loose and fast on my prep, so a highly tuned machine with all the neat bells and whistles, like obsidian, just doesn't work for me.

I use it for all of my note taking whenever I am a player. Linked notes, backlinks and Breadcrumbs really help me remember, what the relationships between NPCs are, who might be close by when revisiting a town, or generally tying strings together. As a GM I find it less relevant to me, since I usually run prewritten adventures.
