I've said it before, and I'll say it again: Apple is sitting on a goldmine in terms of games on the iPhone (well, they're sitting on a lot of goldmines with the iPhone, but this is another). With multitouch, the tilt monitor, the microphone, the networking capabilities, and the camera, this is a device that Nintendo would dream about building (their DS has half the features and it's selling like it prints money). It's the greatest handheld gaming device ever made. And yet because Apple has been so stingy with the SDK, there's not one official native game on it.
Not to mention that the "distribution platform" Boatman is talking about is iTunes -- there's no better way to get your games sold and out there. Hopefully, we'll see progress on this as soon as MacWorld (and as late as February, when the iPhone SDK is set to be officially released). But Boatman is right: the iPhone begs to have some great gaming experiences on it, and Apple, so far, is just not opening the door.
