Apparently I have 101 game on Steam. A lot are linked there from other places and/or 'filler' from bundles. I only have 8 Steam games installed and just play one, FS2020.
I'm thinking of closing my Steam account if I can figure out how to migrate FS2020 to the Windows store. It might be better to wait until I get bored of FS2020 since I've read many horror stories of people trying to switch from the Windows store to the Steam version. Anyway, I don't agree with Steam's policies anymore, won't be buying from or linking anymore games to Steam, and will simply wait for the right time to close my account.
