Hi

I have Rebel Assullt I+II, bought on steam, but I can't get it to sync in GOG Galaxy 2.0 platform, ie the game does not show in my list of owned games.

Tried googling, but I can't find a solution or topic covering this. Any idea/soliutions?

S****'s own client works fine. Why do you need to force their games to launch on GOG's Galaxy client? If you want to play games from other shops, you have to let their clients start anyway.

Well i struggle keeping track of which games i have on which platforms - and seems to me GOG Galaxy is the best solution to have a complete list of owned games.

Found these link that looks to be down the same road as me, in general they import just fine, only a few titles missing, Rebel Assault being one, Xwing vs Tie Figter another.

:(

You can try Playnite. It is free and is an exceptional launcher to keep track of your games. Not to bash Galaxy, but Playnite is a good place to start.
