Idea for a new button: When you're in your libary on a game, for example I just finished Sleeping Dogs again and I want to play a game like it, I would like a button that takes my to a custom store page that shows me game simular to whatever game I'm looking at.
Also I think an AI Shopping Assistant/Currator/Tech Support has a big future on this platform, the amount of titles on the platform is overwhelming with the simple tag system we have now, noone is browsing 1000's of pages with 10 each to find something, just sorting by popular hides all the hidden gems...
It can be a trash game with many players, numbers doesn't always mean anything.
