I am writing mostly because of curiosity. I made an android game inspired by one DOS game I used to like when I was kid. With several added features, like online multiplayer, you can search for "Annelids" if you want to check. (I can't send links yet.)
After initial struggling it got more or less popular, but what is interesting:
About 25 % of all downloads come from Russia and only 4 % from USA. According to Google Play statistics, average in Arcade games is having 5 % from Russia and 13 % from USA. Downloads from other countries are close to the average values.
The game doesn't have Russian localization and until recently we didn't even have Russian translation of Google Play page. We didn't do any kind of promotions for Russia.
I am not complaining at all, but I wonder how could that happen.
Any possible explanations?
