We've already posted a very positive review of Cloud Spin [$0.99], a super-slick Unreal-powered (initially) rails-based flying game that quickly opens up into an even slicker hang gliding game, complete with Pilotwings-style updrafts to hit.
Getting to the hang gliding part requires beating the first three levels, which we do in the video before giving the free flight mode a try. Make sure you either watch or skip to the end of the video to check that out:
It's pretty easy to recommend Cloud Spin, particularly with the second game mode which you could make some strong arguments towards it being better than the "main" game mode. Give it a look.
