All of those games probably could have been done ok except for TPIR.
You might be giving the Atari 2600 more credit than it deserves. I've thought about this for a long time and the only way I think most the games could have worked would have been if the on-screen part functioned merely as a crude game board and the bulk of the actual game playing happened off-screen. There just wasn't enough \"oomph\" in the cartridges to store, for example, anything approaching a useful number of questions for the Q&As. Wheel of Fortune would have worked, of course, but I have my doubts about ANY of the others.
And I'll tell you where John found those nifty pages. It's a tribute site for old videogame programming called The Atari Gaming Headquarters
http://www.atarihq.com . Terrific place, especially for those of us old enough to remember playing with the 2600. The one piece of information that you don't learn from those press releases John found is that The Great Game Company evolved into GameTek. GameTek retained the videogame rights to all those game shows, so even though the games didn't come out for the Atari, most of them (and some others) became the subjects of the earliest PC versions.
