I don’t see Bioware titles on the list. Dragon Age series for fantasy, Mass Effect for sci fi. Since BG3 is on the list, I wanted to mention in case you haven’t gotten to them yet.

+1 to RimWorld suggestion.

+1 for Syncthing, been using it to sync a tablet, a phone and a pc without much problem. Obsidian usually makes a separate note when there is a synch issue, so at least you don’t need to worry about losing your data.
