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
