A few years ago my brother-in-law programmed an augmented reality game where you find treasures in your community. He is a huge Pokemon fan and would have loved to make it about finding Pokemon. He decided against it for obvious licencing reasons but the idea was definitely there and a pretty obvious one according to him.
I hope he enjoys playing the official game and isn't bitter about it even though he insists his game is actually better.
The good life is one inspired by love and guided by knowledge. Neither love without knowledge, nor knowledge without love can produce a good life. - Bertrand Russell A herring's blog Johari / Nohari
