It may have been mentioned before, but the PDF of Melee is a free download if people are curious about the core system.But an $18.00 PDF isn't a big investment, nor a $35.00 bundle of the core rules, plus micro-games, adventures and other add-ons. Or even the core rules in hardback for $35.00 (or $30.00).
While it wasn't for me, I don't think it's a "bad" system. (And I did buy the $100-ish boxed set on a whim.)
