Though I personally feel that mobile gaming has failed to live up to its amazing potential, slumping over the last few years due to an influx of clones and the inherent issues with Android as a viable platform for anything other than F2P, there are still plenty of timewasters to enjoy and the occasional gem too. Plus, you know, all the other stuff on iTunes.
