Some very cursory research suggests that the sales numbers on computer games tend to be about 93% Windows, 5% Mac, and 2% Linux.<p>I&#x27;ll let you pull your own estimate out of the air for how much extra development time&#x2F;money supporting a decent cross-section of popular Linux distributions will take. Oh, and don&#x27;t forget to add in time for testing it, too.<p>This may change if Valve can make the Steam Box happen, but right now it sure doesn&#x27;t sound like a sound business decision to bother looking for those last few extra bucks from Tux. Honestly I&#x27;m surprised anyone releases <i>anything</i> for Linux or for Macs now that I look at the numbers; I suspect we have the rise of cross-platform general-purpose game engines (which this game doesn&#x27;t rely on) to thank for that.
