This game is unique in what it offers and can provide endless hours of fun and entertainment. That is, however, only until you start to encounter the massive grind that makes it almost impossible to enjoy playing. The economy of the game has been made worse with each update in a (in my opinion obvious) attempt to push players to purchase premium accounts and vehicles - the only options there are if you want to get even remotely close to modern tanks and planes without spending at least a couple hundred of hours to reach them.

All in all, wonderful game but sadly ruined by greed and bad decisions. With the game in this state my suggestion is: Don't even start playing - at least not until the Developer actually starts listening to the playerbase.
