I have dozens of iPhone games, and virtually none of them are what I would call “playable.” Of course, that won’t stop me from buying and enjoying them, since they can still be fun, imaginative, and beautiful. They’re also generally in the cheap-to-free price range, which helps make up for the fact that only a tiny minority of them appear to be compatible with human fingers, such as the standard-issue models that came pre-installed on my hand.
