Unity 3D: Mouse Flight in an Arcade Space Setting
I'm not totally convinced the mouse flight rig is the best option in an arcade space setting. The main benefits of this kind of control scheme are kind of lost when 1. You're flying something with a crazy yaw ability and 2. Your guns aren't necessarily fixed forward.
That said, I could see it being more useful on a much slower ship. E.g. with flyable capital ships. Being able to look to where you want to go would be much more comfortable than being locked forward to a slow turning ship. Would provide better situational awareness too.
I am really annoyed the source video was 60fps but Youtube doesn't show it as such.
