I’ll start by plugging Harvard’s free courses catalog as well as Udemy
Edit: Gonna add 2 more I remembered-
Blender - I wish I had more time to learn it, but I did start the infamous “Donut Tutorial” once!
Watch Cartoons Online - Lots of good older stuff!
Oh nice! Finally I can play Backgammon with people (no one IRL ever wants to play)!
There are also Ludo and Parcheesi, which are effectively heavily modified variants of Backgammon for up to 4 players.
