With a sprite, you could take a pixmap and assign it
a direction and velocity. Which was, I suppose,
"perfect for Asteroids" :-/ The color fringes
on everything, would make you puke. The chip had
some limit on how many sprites it could support,
each one having the programming feature. Again,
seemingly tailor-made for Asteroids or Defender.

Asteroids-on-raster, that is. The proper arcade machines used
vector-scan for Asteroids, and IMO looked far better because of that. (I
don't know how they generated their EHT; at a guess, with a dedicated
oscillator. [I doubt with a 50 or 60 Hz transformer! Those were
lethal.])
