It’s a good philosophy, to be sure. It doesn’t take many migrations to realize that keeping your files in open, easy to read formats is preferable.
I also use obsidian, but I do sometimes worry that the linking and metadata will be difficult to work with in the future when the software goes away. It’s all there in the files, but my vault is slowly linking together in interesting ways that rely on obsidian functionality.
I spent a whole sick day blasting through a good chunk of the games a while back. It’s weirdly fun. I basically just bought it for the pin pull game that always infuriates me in ads but spent several hours getting all the stars in the parking lot game instead.
