Conclusion
Total Known Turtle Arena downloads: 3,324
Known Unknown downloads: people can get the game from git and Mageia 2 package repo (though probably few downloads from these).
First available for download December 2009. Average 75.5 downloads per month (44 months). Average 2.5 per-day (44 months * 30 days). It’s higher than I expected, though it’s low when compared other more-complete games.
