Would Obsidian work for you? The notes are stored locally, and the software uses markup for formatting and stuff. You can get it synced to your phone with Dropbox, OneDrive, etc.
I still play Dishonored every year. Those are not realistic graphics in the slightest, but it still holds up pretty well. Why? Style. I would 100% take a “lower” graphics game with style than a 100GB game with exquisitely modeled sandwiches.
Stylistic games also age better than realistic games in my opinion. Look at other 2012 games like Mass Effect, Far Cry 3, and Borderlands. Mass Effect and Far Cry went more realistic, and I think they suffered a bit for it in the long run.
Not saying Dishonored didn’t age tho. It does have that 2012 feel, lol.
Reading this as an Albertan.
