I said so because...
a) In 1985 Eagle Dynamics did not exist.
b) NTTR, for example, was first shown by ED in late 2010 and was a 3rd party project at that time.
c) Nobody was producing consumer 3d graphic games in 1985. Vector and sprite graphics were as good as it got.
d) The computing power needed for 3d modeling was not available on any personal computer platform in 1985. It did come along a couple of years later but only at a level suitable for static models with a limited number of polygons.
e) In 1985/86 (I was 26/27) I was researching the available CAD/CAM 3D modeling systems being considered for purchase by my employer. I have a rather intimate knowledge of what kind of machine it took just to render a simple static 3D object, much less to animate it. We ended up with a MicroVAX based system which supported 8 *NIX based workstations. The price tag was just shy of $500,000, not counting the maintenance contract. A 32MB memory board (a square foot board covered with memory chips) for one of the workstations cost in excess of $10,000, and those didn't even exist when we purchased our initial system.
Date is confirmed for me since I was on the way back from a trip to a local HP office when the Challenger exploded. It was a very long and quiet trip home.
I don't think you are delusional, merely mis-remembering the quality and identity of what you were playing.
