this picture over at Dragonsfoot and I just had to share it. Dave Arneson himself apparently even admitted to loving this particular version of D&D. Note the pre-production cover of the Rules Cycøopedia up there in the left corner.
Anyway, there is a call to reprint the RC over at wizards.com, so go ahead and sign the petition. Rumour has it that this is the only edition of D&D that is so good that WotC doesn't risk reprinting it. We shall see!
