I beta tested it. It got old after about 5 days. Its well made and runs great but in order to get the good tanks you have to have earned credits through either fighting in game or buying them with real money. Some things could only be opened up with the use of real cash. Basically its a slow drain on your wallet as opposed to a one time payment.
Its not a simulator per say more of an action thing. Worth checking out if you can do so for free.
