Pulling the turrets off tanks, snapping gunships in half is great fun but the novalty wears off pretty quick
The level design has been described as repetitive and samey but if you think of it more as a flight sim than a third person shooter then its much more fun because the nature of iron man suits the flight sim model much better.
It does have its faults the cut scenes between the missions being one also the gameplay life is pretty short and after you've completed it there's not much reason to go back to it. In short not the best game ive ever played but also not nearly as bad as some reviews have made out.
