I worked in a restaurant in 81 while in HS. Next door was a convenience store that had Defender and Battlezone. I think I spent half of what I made on those two games for a few weeks. I would sneak out for a game. An addiction. I can still hear those Battlezone sounds in my head 45 years later.

The periscope style vector CRTs use in the arcade Battlezone were a claustrophobia and panic-inducing experience. Glowy unpixellated 3d, narrow field of vision. Unforgettably cool.
