Steam

Could you expand on that pls?

Im wondering how does the excess amount of games offered by a store affect your experience. How would you even notice that?

And - that they were a more closed store was what made them special?

Then I think of GOG I think about licencing, how I actually own a game purchased, how I have a key for it, how I'll still own that game even of GOG stops existing. Thats not true for any of the other stores (outside of physical copies if some sell them, idk).
