Check out the online flight sim (ww2) skies of glry. I just got this game and it is hyper competitive online where after like 5 games i still didnt get a kill. Thats hardcore gaming for u. Oh and ive played it on e ipad 2x so it must be even harder on the iphone tiny screen to get kills. This and samurai 2 on hard mode so far define the genre of non casual friendly games imo.
