Here are my thoughts - I think it was a mistake to try to do this in order of approximate original release date. Temple of the Frog is not really a true adventure - its a location, and not very well detailed at that. I think a better approach would be to make a campaign sequence out of a group of classic adventures and take them one sequence at a time. For example - T1-4, A0-A4, GDQ1-7, and then top it off with S1. Then the next sequence could be B1 and B2, then X1, then a couple of the C adventures, and then...well, you get the idea.
I am currently working on a revised version of the setting, with a more coherent timeline and more detailed history.
Any thoughts?
