Everything from the graphics, music and sound to the tank simulation and much more has been improved. At the same time, there are still areas for development, such as the AI, more maps, the user interface, the visibility of your troops, and a more content-rich multiplayer mode. There are also certain aspects of the balance between the troop types that need reviewing. For these reasons, my rating lands a little lower than what I would give the fourth instalment today, with all content included. When it works, it's good, but at present there is room to improve even further.
