You're comparing one of the best, most-influential games on the NES with a rush-produced cash grab on the Atari 2600. There were many better games on the 2600. Also, the NES came out six years later than the 2600, so it's way easier to make more detailed and more interesting games for it.

Well yeah, it sounds like you are still agreeing to my original point that Japanese ingenuity, at a later time, successfully rescued the industry from a crash caused by said cash-grabs. That is exactly what happened! I still remember the panicked industry reactions here in the US when Nintendo showed up and raised the bar tremendously. What were your favorite 2600 games?

Yet they revived the industry because of strict licensing and the ‘Nintendo seal of quality’ label that assured you that if you bought a game it wasn’t a rushed stinker.
