Wanna *play* Battlezone with the 3D wireframe tanks? Rebellion bought the license and made a Playstation VR version (now on PC also since a while back). It has a Classic Atari Battlezone mode, which can be played either with "modern" strafing hovertank controls or the old tank track controls.
It's pretty sweet, and as of yesterday you can play it flat (non-VR) also.
I mean, there's a web version somewhere if you look for it, but it requires flash, and buying a PSVR rig might be cheaper than what flash could do to your system :-)
Expensive - moderately. Useless - who cares? Fun - absolutely. Sturgeon's law applies as always, but as time goes by there's more and more stuff in the remaining 10%
