more data, more data, more data!
Kill Ten Rats informed me that Edward Castronova (and friends) have published a paper (pdf) on the Economics of EQII, using actual game data. Lots of it:
The dataset is
a comprehensive capture of the actions and communications of hundreds of
thousands of players over time. This dataset contains more than 300 million
individual transactions: lists of thousands of items sold, with purchase amounts
I'd like to draw your attention to that number again: 300,000,000 individual transactions.
With that kind of data I'm amazed the paper is only 24 pages.
