Since the 8.0.0 update, people have been complaining lately, about why Rilisoft has increased prices, added a new gem system, and let more hackers roam the servers with gear. The answer to this; since the Great Recession in global markets around the world, Russia's current financial crisis has caused the Russian ruble to decline in price by other foriegn countries, causing a debt. The debt had caused many Russian companies (including Rilisoft because it is based in Moscow, Russia) to pay the debt by increasing the cost of interest payment in dollars and/or other currencies.
Because of Rilisoft's increase of payment for the debt. They are forced to increase prices and incorporate a premium currency system, they hoped that will encourage users to buy the new currency and pay the increased prices, along with the new weapons, so they will have an increase of money to pay off the increased interest, in conclusion, Rilisoft needed more money so their company and the game will survive the ongoing financial crisis.
This thread has been created in hope to answer the questions about the changes in the game, the current situations Rilisoft is facing right now, and also the hope of the community's support and understanding of the changes with Rilisoft.
