What a fascinating new platform the iPhone is. Everything from the quality of the device, (the iPod Touch being equally valuable), to the way that you buy games, to the price and range of them. It’s brought back a way for independent developers to get their products easily to people, and all of the pain has been cut out of distribution by Apple. It has some of the feel of the 8 bit early games days.
And the other joy of it is the way that games are successful on iPhone by just being good games, entertaining with good gameplay. There is no domination by big budgets and big rich studios. This may change over time, but right now, it is very refreshing.
