I've been playing this game now for over eight months and spent about $20. The free to play format is brilliant. You can choose to spend as much or as little as you want. I've spent money on permanent camo and to trade skills / perks. If you don't want to take the time to play to grind out new tanks you can spend money which works out to the equivalent of buying a "NEW" game. You do not have to pay to win. I'm an average player and after 4000 games I'm around 60% win rate. The other really neat thing about this game is the continuing evolution. From new maps and tanks to changing daily ops and competitions. The excitement just gets better every day!
