Wargaming has launched their promised new Unified Account System is now live, allowing players to access all their games from a single account. They say: "Now live in World of Tanks and World of Warplanes, the new service spares players from paying for premium status in every project, spreading its benefits across other company’s titles and providing players with an increased experience and credit accrual rate in-game." Here's more from the Wargaming website:

With a single unified account, you’ll have direct access to all of Wargaming’s MMO titles in a single portal. Logging into your Wargaming.net account will automatically log you into all other Wargaming-related projects, including partner and fan websites that can be reached via the secure OpenID authentication.

Already registered with World of Tanks or World of Warplanes? Your account automatically becomes your Wargaming.net ID. Use it to access any title you want.
