Russian Department of Finances is planning to ban “surrogate currencies” in Russia. The law is clearly aimed at crypto currencies, such as bitcoin, but it is written so vague, that it might affect any other virtual (i.e. fictional) currency as well, including in-game currencies.
Apple Insider here worries that it will effectively put an end to in-game purchases. It probably will not, but game companies will have to replace their “gold”, “crystals”, “hairy gophers” with Russian roubles.
Or maybe not, you never know with Russian laws.
