Games that personify/define a console to you

I guess I'll do the deep dive to the 2nd gen.  Donkey Kong was the pack-in game for the ColecoVision and was heavily leaned on in marketing to support their "The Arcade Quality Video Game System" tag line.  Donkey Kong helped move a lot of ColecoVision units in a short period of time, breaking Coleco into the home video game market which had been dominated by Atari up to that point.
