Very addictive but sometimes frustrating gameplay. The designers really push you, even annoy you until you pay! As the game and your rank progress it becomes almost impossible to compete with paying players. They have better tanks and ammo. Shame! Also frustrating is that the tanks have zero historical accuracy. E.g., a light Japanese WW2 tank is stronger than a US medium tank of the 1960s. The controls are sometimes difficult. Not really possible to steer and turn turret at the same time.
