Since this thread seems to have evolved into memories of home games, I might as well share why I started the GSHGHP, or at least started collecting the games as an adult.
I had 'em all growing up, or at least all the ones from the mid 60's through the mid 70's. There's an 8mm home movie of me opening a Christmas present of a Concentration game when I was three and a half years old. (Family legend says that I was making matches back then, even if I didn't understand what the rebuses were all about.)
When I went to college, the games stayed behind, all piled into a wooden storage shed behind our house. One day my father was burning leaves a little too carelessly, and the whole shed went up, all my childhood toys and games with it. Honestly, while I still loved game shows, I hadn't really thought about the old games as being collectables, so I didn't miss them that much. Still, the more I thought about it, the more I thought it would be an interesting challenge (this before Ebay) to see how many I could find to replace what had been lost.
In researching and hunting to replace what I had, I began discovering how much more there was out there. A couple of huge breaks in my research were finding an article about game show home games in a fanzine called Spin Again, and meeting Bob Zager (a member here), another avid collector from Michigan.
I developed what I thought was a definitive checklist, though new finds kept popping up and I'm still not entirely positive I've found them all. It was a personal project until the internet came along, and now it's one of the oldest game show web sites out there.
(I said ONE of the oldest, Mr. Lambert. BTW, congrats on reaching a decade with the OGSP.)
And now you know the rest of the story.
