I don't know how many computer science majors flunked out because of 'HACK' on the unix box, but I know that you could log on (using the super speed 300 baud modem) at 3:00am and there would always be a few (usually the same) playing. I did love that game, and my son with his xbox still talks fondly of the experience.
I still have my 2600. My nephew wanted it, I told him to take a hike. I have Adventure, River Raid, Stargazer, or Starfighter or Star something, Breakout and maybe 10 or 12 more games. I though the Activison games were the best as far as graphics and such. My father-in-law has the Mattel Intellvison, with that Navy game everyone was talking about, Olympic Skiing, Golf and a few others
Me, I'm still a VAX systems manager. No Qix on them though
