The DS4 speaker added a lot in Alien Isolation while using the scanner. That also used the light bar.
It would be nice if games started to make more use of the track pad. The most 'advanced' I've seen so far is in Terraria, zoom in and out with 2 finger motion. I hope Tropico 5 supports the track pad as a mouse cursor, but from the trailers that doesn't seem to be the case.
