WizKids are the company behind the "latest" card/collectible craze - Pirates of the Spanish Main (technically the name of an expansion/new version) - and they are rather open about the system; you can view flash animations of the rules and download the full rules, as well as views of cards and listings. So the only reason to buy the actual packs, is the collectibility: the combination of the art, quality and "wonder what I get" factor. Cool. Maybe something for the balcony this summer to supplement our Harry Potter obsession (fueled by radical discounts on the packs, 10 NOK vs normal 50 NOK )
