Remember back in the 70's-80's when Atari's came out and games were very simple? Like Pong, Space Invaders etc? I'm trying to remember the name of the game that had block-tanks, planes that moved across the screen, shoot at each other, and the target that got hit would spin in circles. It was a very basic dot-matrix brick-style graphic game but some how still a lot of fun to play. At least it was back when. You even had the option of having doubles.
