Seems to me back then there was at least one vendor of
a vector-scanned
(as opposed to rasterized) game. Or at least the product announcement
was made--I don't think I ever saw one up close.
Never saw one? What a shame.
The BattleZone emulator for Atari Home Machines was
a good substitute, better was the Vectrix/Vectrex, also a
home machine from the 80's which was an actual vector
machine architecture.
