Over in Parkes Shire, Australia, we've just released a Creative Commons-licensed tabletop roleplay game for all ages. It's easy to learn, quick to play, and students can add their own rules to make it even more exciting. You just need a few paper cut-out characters, a measuring tape, plus a handful of dice and Lego bricks.
You can download the game's 8-page PDF, including character sheets, here at the Parkes Library "Dog-Eared" website:
Cory Doctorow, whose work inspired the game, featured Parkes' Tabletop Superheroes on BoingBoing this week.
Feel free to share, enjoy, and remix your own versions!
