So for Diablo and Grim Dawn, just zoom the game camera in. The game then plays like an over-the-shoulder experience and is surprisingly very immersive this way and everything is big enough to play an hour or two without much eye strain. The 6.7" screen is very wide and feels natural. When I played the first time it was just an experiment and I expected the worst but I soon discovered playing like this is much better than keyboard and mouse. The only upgrade from this for me would a $2000 laser projector with high refresh rates + controller.
