Havardblackmoor

Dave Arneson's Blackmoor and Gary Gygax Greyhawk are the two most influential campaigns on early D&D. Do you have insight on any other campaigns from the early history of gaming that you would like to share? :)

Probably true. The fact that Dave was 9 years younger and still a student at the time has also been cited as a reason for him not being more involved from the beginning.
