Wargaming.net announces details on how the economy will work in World of Warplanes, their upcoming flight combat MMOG. Word is the game will use the same system as World of Tanks:

The new game recently announced at E3, will have the same economic profile as the highly-acclaimed World of Tanks, with Gold, Credits, and Experience as main currency to gain and spend for continued advancements.

World of Warplanes will feature a global interaction with World of Tanks, which will begin with sharing Gold and Free Experience between the two games for players, who have registered accounts in both of them on a single email. This feature will allow Wargaming.net community to plan their expenses and leave exactly the amount of Gold and Free Experience they want on either of the games.
