I know I brought this up not too long ago, but the answers weren't exactly what I needed.
It was my fault for not being specific enough. This is what I should've asked:
Was there ever a time when a home console came out that it matched THE MOST ADVANCED arcade game of that year? If not, by how much did it fall short- or, in the unlikely event that it was ahead, by how much? For both the ColecoVision and Atari 5200, as well as the Arcadia 2001, I'd imagine Zaxxon was the yardstick. You could even bring up the Vectrex, if you are talking about a 1982 vector game.
Clearly, this is a question for the more technically-minded here.
