Yes the games are VR games, and no they do not require VR controllers. Almost all of those games worked with previous versions of piplay without any problem.
Anyhow, i got the games working using this thing called "Revive". To my knowledge Revive is supposed to make oculus games work on htc vive, but the games i tried to play without revive are compatible htc vive, and still needs to be used with Revive if used with Pimax. Don't know why it is that way but that is how i got it working if someone else is having the same problem. The Piplay also does not recognize the headset, eventhough it says that the USB and HDMI is connected.
