I really don't think you could run that without the DCC RPG rulebook.
Isn't this true of several of the free RPG day materials? I haven't seen Paizo's module this year for Free RPG Day, but the ones I have run would require the Pathfinder rule book to play. The module isn't really self contained.
Yeah, this is an odd quirk in Free RPG Day materials. Many of them are quickstart games, which is kind of what the original intent was "back in the day" when they started a few years back (along with free dice or other stuff that didn't need a specific set of rules), but over time more and more of the freebies have been mini modules.
Some of the best non-DCC products I can recall are quickstart versions of Mongoose's Traveller, TLG's Castles & Crusades, and Flying Buffalo's Tunnels & Trolls. You could really crack open the booklet and actually play a module from scratch. Very well done. This year I saw a quickstart rules set for Shadowrun, but I think the rest of the freebies were modules rather than rules.
Last year's DCC "Adventure Starter" had at least some words of wisdom as to what makes the DCC RPG different from other games and some advice on how to play, but of course the Beta download was also free. This year's product, like most of the rest, was a couple of adventures.
