Linux Users More Likely To Pay For Games?

Teppy writes "I noticed something unexpected the other day when reviewing the subscriber counts for our MMORPG, A Tale In The Desert. Of everyone who tries our game, Linux users are definitely more inclined to pay money to subscribe. In fact, overall, about 15.6% of Windows users who do the free trial will subscribe, while among Linux users the number is 19.3%. Furthermore, Linux users tend to remain subscribers for a longer time. Are we the only game company noticing this?" Is this down to loyalty, choice, or other mysterious factors?
