This is hands down my favorite PC game ever! There are good and addicting game modes, like Team Base Destruction (my fav) where you must grab a bomb and fly it to the opposing team base and drop it on their base. Also Ball, which is like soccer but with planes! And of course Free-for-all/death-match modes. The real fun is the online-play of course, where you can level up and unlock different planes and "perks" (weapons, armory, etc.). Try the demo for yourself and finish the training (they have easy, medium, hard and expert difficulties), and afterwards if you feel that this could be a decent game, then just buy it because as said before, online is where the fun is at. It gets millions of times better than the training.
