For some reason, I don't think FPS games work on the iPod/iPhone. Don't get me wrong, I love AlienMangle, but I really don't like the controls that have been proposed. With the coming arrivals of Prey and Hill Billy, I really don't know if the FPS genre is worth buying. I love the App Store games because they are fun and addictive. I bought Zombieville USA yesterday and it was quite fun as I didn't have high expectations. I just think that it is a waste of money to buy games that aren't suited for the average iPod user. I will still check out Prey and Hill Billy, but I really don't have high expectations. Any comments?
