http://worldoftanks.com/ This game is by no means new, and it does have micro-transactions. That being said, you can enjoy a pretty balanced system for something that's free 2 play. There ARE premium tanks, but they aren't the best tanks in the game. They are just, well...easy to get and pretty good. Anyway, I love World War II games. I like them from the grand strategy board game or PC game, down to the first person shooter or RPG. If you've ever wanted to jump in countless different WWII vehicles (many of them prototypes) and beat up other people who love doing the same...this game is a blast. It is PvP, but it is 15v15 pvp, so you do have a team and sometimes they even work together! I suck at it, but would be honored to be in a platoon (a group that does battles together) with anyone from Atari.IO anytime!
