GeForce go also took down almost all of it's titles due to licensing issues where Nvidia were too afraid to upset their partners, which shows there is no business here and they should never have invested in the first place.

But at least Nvidia's initial conceit was that it would piggy back on someone else's content ecosystem rather than building their own - building your own gaming content ecosystem is a) incredibly hard b) a fifteen year plus project and c) costs a hundred billion dollars. Google weren't willing to do those but launched a project that needed them.
