There were some EM games in the late '60s or early '70s that I haven’t seen around, and I can’t find word of them here, but I think they were popular and well distributed.
One was an airplane that flew on a rod, going around horizontally in a circle above the playfield. You controlled the height of the plane, as it went around. The game was to navigate the plane through an arch, over a barn, and maybe under a bridge or something.
Another was a shooting game, where you are a gunner shooting down three airplanes that, if I remember right, were painted in fluorescent paint on clear discs. They moved around the background erratically, making them hard to hit.
Why don’t we see these around being restored?
I guess they were just EM games, but maybe there is a better term for it.
