I don't suppose someone is doing another Paragons from the Past event like they did a few years back at Gen Con 50?  The event had several adventures from 2nd, 3rd, and 5th ed D&D, Battle Cattle, Paranoia, and a few others.  All had been created for the old RPGA and had fleshed out pregen characters.   I'd love to get in on that again, but I couldn't find them last year.
