Not exactly a high quality AAA title, lacks very basic settings you should now expect from any PC game, resolution settings at the very least, but sadly, nothing, so you are forced to play in a square box at some pretty poor looking models.
The game play itself is pretty solid, I assume this is very basic flight simulator stuff though, taking off and landing is very easy, it takes a lot for you to stall your plane. There is a wide selection of different planes to choose from at the start of your missions, each having their own different stats, strengths and weaknesses. I won't spoil too much, but one of the planes is so much better than any of the others so the large choice is kind of pointless once you work it out.
There is an essence of customization when you reach certain goals, you will be granted experience points to improve your character (planes). I focused on agility and luck (which increases your critical shot chance), and this turned my plane into a little nippy bomber that could avoid pretty much any rockets!
The main story took me about 8-9 hours to complete, and it was quite an enjoyable play through. There is plenty of re-playability in the arcade mode, which is where I spent most of my time.
I would recommend this game, however if you are playing this expecting a crisp AAA experience, you will be disappointed, if you go into this with the only expectation is that you are going to fly a plane and blow stuff up, you'll enjoy it.
