Exactly. I can confirm that the most of the gamers in Russia aren't ready to pay $60 for a single-player game, even the game like TW3 (I'm personally not including in this group of gamers). It's like a 1/10 or even bigger part of monthly wage in the average provincial town. At the far regions and CIS situation even worse, much worse.@jerf
Lowering the price of games in markets where avarage income is lower, actually increases the money you make from those games, because they are no longer seen as a premium product.
In last years financial situation slowly coming slightly better in Russia, but psychological barrier for this kind of expenses is still present for most of people.
So, price reducing is a really smart move for Steam and GOG.
