If you haven't played them the original Fallout 1 and 2 (the Fallout 2 Restoration Project is a big recommend) and Arcanum are classics as well.

Endgame: Singularity is a fun (and sometimes very frustrating) small strategy game worth checking out.

The Dark Mod is basically Thief but really well done with a solid amount of (fan) missions to choose from. Speaking of I should play some of it again.

I actually went back to (neo)vim because I found vscode was not quite keyboard-driven enough for my wants. But especially with neovim you can torture it into basically being a IDE with all the available plugins out there (e.g. in my setup I have highlighting, code completion, reporting of syntax errors and forth)
