Greetings, You may enjoy Dimensions The Game by RJDJ. It is a simple game constructed around the mechanic of augmented sound distortion similar to what is used in their other apps including the excellent Inception movie app.
We've worked on a few AR apps (not all games) : Hoops AR is a nicely polished basketball game http://itunes.apple.com/au/app/hoops-ar/id473195066?mt=8 And we just finished work on Floodlines for the State Library of Queensland, which shows the under water areas during last years floods. http://itunes.apple.com/au/app/floodlines/id511208257?mt=8 For that one you need the postcards from the exhibition, if you're in Queensland - I'm hoping they'll release them for download shortly. Also (not developed by us) there's Chromian Wars http://itunes.apple.com/app/chromian-wars/id473788469
My favorite continues to be Duck Hunt AR (long gone) I'd highly recommend ARDefender (Hint: print as big of a template as you can and place it on the foor!) Star Wars Arcade is fun.
