If they could figure out a way to do this for.... gasp..... console games at a reasonable cost? NVidia has a winner. Of course, they would have to fight it out with Microsoft and Sony over this but I could see them coming to an agreement with those two companies if it was properly pitched.
As an FYI the writer of this article is, from the looks of him still having access to Pixeljunk Monsters(No longer on the current GRID) is using the now outdated GRID app(which is still having the servers kept o for a few more months so players can finish the games) while the currently supported grid servers can be accessed through the Shield hub app, which with the most recent update, has the CURRENT grid library built right in. Meaning there are the 22 games(Later on in the day, 24 games) listed by nVidia.
