Despite being on the market for less than a year, the iTunes App Store is already overflowing with games. However, even with this huge selection, developers aren't doing a brilliant job optimizing their games for the iPhone. For example, some developers still over-implement the iPhone's accelerometer, which doesn't function properly if you're moving (or, say, riding in a vehicle). Developers need to make iPhone games easy to play (that means no control schemes that make your fingers block out the screen), not very time consuming (think Call of Duty 4, not Fallout 3), and super addicting. iMob online hits all three of those spots soundly.
