Dal Segno, Wagamama High Spec, Kinkoi, Subahibi, Beat Blades Haruka, and Grisaia Phantom Trigger Vol. 1 have all been played so far on the deck. Basically, all you have to do is add them to Steam and place them on the deck. Since the majority of video games can be played with just the left mouse button and some mouse tracking, I hardly had to build any mappings.
