clarry: That said, there is a way to couple native clients & wine games:
Games shouldn't need to run *through* Galaxy. Games can communicate with Galaxy, even if they live in a prefix. The wonders of IPC/RPC. I haven't used Galaxy but I've heard Galaxy 2 made big noise about being able to launch non-GOG games too, or something like that.. this should be a no brainer then.
I'm clearly no computer scientist, but are you saying you could get all the features of the Galaxy client and be able to wine a specific game? I don't think so - you could wine a specific game, by bypassing the Galaxy client altogether though.
But what exactly would be the point of a native client then? If you bypass the client to run the game through wine?
A native linux Galaxy client would then just act as a glorified downloader, and you would miss out on all its features like achievements, gameplay tracking, auto updates and...I struggle to think of anything else.
My point is that a native Linux Galaxy client is often requested (biggest galaxy wishlish by far) and is considered a sign from GOG that they support Linux, whereas in my view it would only complicate things and I would deem it largely pointless. Sorry for pointing out the elephant in the room guys, that's just my two cents.
However, I completely understand people who think linux native games on GOG could use some extra work and better support. That's the other half of GOG linux support, of course, the support for native games.
