Hey Elza!

Yes, in time you will able to add any Steam or GOG games (made by Neocore) to our ' "Virtual Shelf" on your personal profile page (it's PINNED on our DEV-ROAD-MAP, so in the future this feature gonna be active, but sadly; i can't tell you an ETA for this). 

As you can see, the Community HUB (and all of our online contents) are under development too, so please be patient, we are working on a lot of cool features in the background! : ]
