I'd struggle to choose between Labyrinth 2, Defender Chronicles and PathPix Pro. Then get killed in the process.
Rogue Touch, Sword of Fargoal, or iNethack. one app, hmmm iNethack. hands down, you can play it forever. http://en.wikipedia.org/wiki/Nethack
I would totally get Distant Shore. Even if nobody receives my SOS message. It would just be so hilariously ironic.
who needs real sand when I have VIRTUAL SAND!!! awesome. Now it is time to wander around an virtual beautiful island because on the real one the campfires don't just make themselves like they do in the game! Ahh, such a peaceful way to spend the day on a tropical island...
