the one thing about 1st person would be the sword. in 3rd person, the sword is held directly in front of the face of the robot, so it would be cumbersome in 1st person, that's all :P

So if the game was in VR wouldn't you want to actually change the controls so you swing the sword manually with your motion sensor controllers? :)

I think some sort of Clone Drone branded experience could work in VR, but there would be a large amount of exploratory design work to make it fit that format well.

Do you have any examples of cool sword fighting games in VR?
