I've previously owned a ToTAN and would definitely buy a ToTAN remake. Surprisingly, I received a lot of grief from my neighbors when I sold it. I did the best I could with it, I even installed some Chestnut gold-plated armor. But the boards and connectors were kinda burnt from being on location years ago. Imagine if CGC turned this one over to Lyman for some extenda-code. Wow!
TOM and BBB were more novelty to me in my brief experience on them during a few visits to the PHoF (TOM) and at an Expo (BBB). If the other group would get off their arses on Kingpin, I'd probably be in on that one too, FWIW.
Also, as a wildcard, I think they only made a few over a thousand Champion Pubs, and probably only a smaller portion are still in existence. Most likely, I'd buy that as a remake too, if it were offered.
