Shhh, just don't tell the Galaxy team :P

@Yepoleb, I always appreciated our community involvement and work done around GOG. Did you get to implement game time tracking (this in particular is not SDK I think), achievements or other features in Comet?

Technically I'm not an expert on SDK, so I can't say much about reasons for it not being openly documented etc.
I presume for Steam it's different, since anyone should be able to publish a game there, so it was a priority for them.

I understand that this conversation have already happened, so I don't see a point of me actively joining in it. Sorry. I will remember about this and maybe ask someone over a coffee. If I get to know something obvious that's missing in communication, I will tell You guys.
