I don’t think it does, but I would pay for this.

Are you able to pull game categories or genres with Heroic or Lutris? For example, to search for local multiplayer games, puzzle games, etc…

How well does https://www.protondb.com/ hold up when checking Proton compatibility with GoG?

Nice! Valve has done a lot for gaming on Linux, its one of the main reasons I use Steam.

What do you recommend on GoG?

I wouldnt pay for anything full price.

Linux has gotten incredibly better for gaming. Now Bluetooth controllers connect just as easy as Windows, and Steam has Proton built in so that when you run a Windows only game, Steam will automatically install the appropriate Proton and Wine software – just make sure to turn on compatibility mode in the Steam launcher settings. Every game I ran so far runs fine on Linux.

It couldn’t be a better time to switch to Linux.
