I’d like to get back into playing video games, but I don’t want to have to sign up for an online service like Steam or Ubisoft Connect.
I love technical sandbox games like Scrap Mechanic, especially if they have a “creative mode” that allows me to just make stuff.

If you’re worried about DRM then look at GOG.com - they sell DRM free games, and you can download the installers direct from their website if you don’t want to use their client and want permanent backups. The installers are not online either. I have a large library of classics and new games from them.
I came across GOG just the other day. Looks great!
I think itch.io might allow game purchases without any account, depending in the game, but even getting drm-free games is almost always going to require some kind of account somewhere. There’s always the “high seas”, but that’s not something everyone is comfortable with.
GOG is probably your best option for completely DRM free games, and fwiw, a lot of Steam games don’t require you to use Steam to launch them. A fairly thorough list is kept here: https://www.pcgamingwiki.com/wiki/The_big_list_of_DRM-free_games_on_Steam
Minecraft.
You can get partway to Scrap Mechanic with Minecraft and the Create Mod.
Quite a few, actually. And it’s worth mentioning that many games, while sold via steam, can also be bought directly from the makers. Factorio and Songs of Syx come to mind.
