Its not Foss, but gog.com is based in Europe. It offers DRM free games. Lots of old games, but also tons of new games as well.

I also recommend Heroic Launcher - it can be used for Amazon and Epic if you have games with them, say free giveaways, but is great for GoG and manually adding installed Steam games. With some finicky steps I managed to get Sims 4 to launch from it. The FOSSibilities are endless

If you want FOSS you don't need a central platform/launcher, most have their own github/similar page.

I would recommend CDDA.
