I just wanted to fly current Jets, for a decade this game didn't have them so I didn't play it. I also don't have the insane amount of time to grind up to those jets as a "Free Player" I did however spend some time learning each era of planes and paid my way through the later grinds and what I thought would be stale game play. Needless to say I decided to open up another jet and have been playing the French tree had fun with it.

So all in all I have the US, Swedish, and French air tree's fully unlocked.

If you're worried about progression, the game is designed to make you just mad enough to either break things or never play it again unless you can throw your wallet at it from time to time.

If you enjoy old school planes, tanks, ships. then this game is great fun!
