This is probably the trickiest post I've ever come up with. There are so many variables, it may be impossible to really answer.
Ever since the earliest "dedicated" Pong home console, we have had game systems that were intended to allow you to bring home arcade games.
However, even back in the late 1970s, arcade games were usually at least a step ahead of home videogaming technology.
In my case, I'm thinking in particular about the ColecoVision and Atari 5200, here's where the problem comes in: the next game I'm writing a review for is CV Carnival. Until the appearance of Opcode's fantastic Space Invaders Collection, this was absolutely the best arcade-to-home translation for that console. And Qix and Berzerk were such games for the 5200.
I guess the problem is that arcade games themselves are so uneven. Some "push the envelope," while others are not nearly so sophisticated. Zaxxon, Space Panic, Qix, Astro Blaster, Carnival, and Astro Fighter all came out within a couple of years, yet you could hardly say they were all of equal, or even similar, levels of technology. Even games of 1982 alone were like this. In the mid-1990s, Sega was supposed to have come out with something for their arcade games that was so far ahead of anything else, programmers at the time figured it would be at least 5 YEARS before any home console could handle it.
And the years 1982 through the CV's effective run showed a techno-improvement in arcade games. So, considering the "learning curve," did it gain/lose ground, or break even?
You also have to keep in mind that home consoles often deliberately fail to use their fullest abilities. Of course the CV could have handled a four-screen version of DK and DKJr., complete with all gaming elements (if not the intermissions and such?).
The question I'm asking is this: throughout the years, and especially now, how far behind were/are home consoles compared to the arcade games of their time? This is for the more technically aware here.
