Nice discussion post, and thanks for mentioning it on my cryptokitties post! I have also been a collector of many physical things for many years... Trading cards, records, sneakers, and now cryptokitties ;)

Collectibles and digital scarcity is something we've never had before. With digital files, there is no breakdown in quality of say audio recordings when sharing, whereas there would have been some quality loss in dubbing to a cassette tape in the past - a fact that made p2p file sharing incredibly attractive.

At the same time, owners of content (particularly music labels) were up in arms about this - how could they secure their content that they invested time/money to create and market? Only now are we starting to find ways to make something both digital AND scarce, which is huge! I don't say that because I'm in support of institutions walling off content (I'm an open-source guy), but it is a much bigger technological development than many acknowledge, and we are only barely scratching the surface so far. Digital collectibles and games are awesome, and are paving the way for much more serious uses of the tech - I'm thinking digitization of physical assets like real estate, vehicles, identities, etc... We are at the start of some very exciting times!

Gamedex looks like an interesting use case as well, curious to see how it goes. Is there any information about what the trading pair with GDX might be on exchanges?

Keep up the good work :)
