Be sure to check out Grognardia today, JM has posted a link to an ancient wargaming fanzine (which is huge, btw, 180-ish pages!). In the article Gary lays out, in five easy steps, how to prepare your own original campaign. Its an interesting read, at least to me and anyone else who is also fascinated by these little glimpses at the "olden days".
Interestingly, it says something about the emerging popularity of D&D at the time that this was the article chosen by the editor to place within a reminder for subscribers to pay their bill: " -----> More than 50 of you should renew their subs - please do it soon!" ;)
