What the title says pretty much! I know I'm not very active on the forums/in-game anymore xD but I've been looking for a flight simulator game on iOS (I have version 7 and will get 8 when it's released soon) that has pretty good graphics, is free (must have), and doesn't require you to pay for the awesome planes (planes larger than a small leer jet or a little crop duster... you know.. big ones xD). This may be a bit of a stretch, but help me out if ya can Thanks!
Try "Metalstorm". It's a modern dogfight simulation with campaign/survival modes. You can purchase upgrades with in-game money, and it's a lot of fun. https://itunes.apple.com/ca/app/metalstorm-online/id425746946?mt=8
I play x-plane hdef-4g. It is rather expensive (20 bucks, might be 10 now)as far as ios games go, but it is much better than Metalstorm. In metalstorm , you fly fighters only. In x -plane you can fly passenger planes, fighters, gliders, sea planes, and even the space shuttle. Because of the high upfront asking price, you aren't being constently pushed in-app purchases, there aren't any in the game. There aren't any missions, it's just about improving your skill as a pilot. If you get it, you won't be disappointed. https://itunes.apple.com/us/app/x-plane-hdef-4g/id380872432?mt=8
