People mix the two types of payment. Payment directly to SE and payment via Steam. If the first method uses a set of international currencies with a fixed price for a specific currency and all local currencies are converted into them, then the second allows regional prices by agreement with Steam. SE itself has never done regional pricing.

Therefore, talking about discounts for Ukraine in SE is meaningless. To do this, SE should reduce prices for all players in EUR or add Ukrainian currency along with a bunch of problems on converting and withdrawing it from Ukraine.

Sorry for the bad English.
