Steam's latest update sounds like a step in the right direction for regional pricing woes
The mystery of what you should price your game is one that I am sure will continue to remain mostly unsolved. There's just no right answer, and to make matters worse, there's currencies other than your own to consider. On Steam there have been plenty of occasions where regional pricing differences haven't gone down well, primarily due to games costing too much based on local wages. However, a new Steam update should now make it easier for devs to set better regional prices.
