It's the achievements for me. Achievement Watcher doesn't work on GOG games installed offline.

I usually grab clean steam files on cs.rin and "crack"(my vocab sucks) the games by myself by using goldberg emu. Problem is the games I want isn't always uploaded and updated unlike Scene releases so I instead download from them if this is the case. Scene release aren't pre-cracked when you download them. You'd still have to copy the steam emu on the game directory first before you could run it.

Also, anyone who owns the game on GOG could just share it by downloading the offline installer on GOG Galaxy. There's no cracking happening so I think it's not Scene's job to upload DRM free games. We already have gog-games and torrminatorr doing that.

I guess the reason why Scene still cracks steam games that are also released on GOG is because of tradition. Plus, it's nice to have some other options.
