The executive explained that Wargaming is working with Microsoft to streamline its certification and update processes ahead of World of Tanks' launch on the Xbox 360 this summer.
"The good thing is with online games, sometimes if you screw up, you can do frequent updates," Kislyi said. "But one of the biggest challenges with Microsoft was the frequency of updates because the QA process and certification process takes an extremely long time. Totally unacceptable for a meaningful free-to-play. We are working with them to do quicker updates."
World of Tanks will be a free-to-play title on Xbox Live, though it won't be entirely free-to-play, as players must have a Gold subscription ($5/month) to play the game. Kislyi said last month that the company must "tolerate" this requirement, which he is "not happy about."
