Good source for linux native games ?

I ran a quick search in this community and couldn't find anything on this topic.

I'm gaming on linux, with a mix of official and alternatively-sourced games. I've recently noticed that GOG has an OS: Linux filter and I found some titles that I could like in that list.

I tried the sites listed in the megathread, and I did not find a place where I could get these linux versions.

Has any of you looked for the native linux versions of GOG games [edit: pirated versions] and found a good place for them ?

Clarification edit (some responses helped me realize my post is ambiguous) :

• I'm not looking for linux-native game lists, I've got that already
• I'm not looking for legitimate platforms on which to buy linux-native games, I've got that already
• Playing games using proton is playing with a compatibility layer, not playing native
• I'm looking for unofficial ways to acquire linux-native games, and I'm aware these are quite rare for resons well stated in some comments
