Another great platform other than Steam.

can we give aways GoG games here ?

GoG (originally Good Old Games) is an online store / platform that specializes in DRM free games. They started out with only very old games + the Witcher franchise (because GoG is run by the same guys that made the Witcher) but over time they got more and more newer titles.
One of their big advantages (beside being DRM free) is that they tweak old games to run on modern systems (usually better than the Steam versions).

GOG is a completely different service focused on DRM free titles and working with old releases to get them into a state that will allow current systems to run them.

GOG and Steam are run by different companies which is why the same games aren't shared between services, but GOG sometimes has promotions which allow users to import part of their Steam library so they can own the game on both services without buying it twice. The most recent was for the Saints Row titles.
