[citation needed] for that assertion. Atari 2600 is extremely limited in the number of sprites available on-screen at the same time. If you've played Pac-Man then you know that 5 is too many, because all of the so-called "ghosts" are actually flickering. They're doing that not for a spooky effect, but because they can't be simultaneously displayed. That sort of sprite flicker doesn't happen in Pitfall!
