I just had to try Pac-Man, so I bought it. Hard to tell how I'm doing on my iPod Shuffle, though. I think Pac just ate Blinky.
I do wonder, though doubt, if they'll play within iTunes, like TV shows do now, turning your iMac into a iPod Advance Game Player. Could this enable the next Pippin?! Sure hope not.
Hrm. Now that I think about it, I suppose this is exactly what I'd asked for a while back. What happens if you think of and program for the iMac as a platform? Matt's wondered about an iTunes method of delivery, a la Steam, but friendlier. Certainly Macs have the wherewithal to easier compete with Xbox, etc's new classic game downloads style of play.
What do you want to bet some enterprising developer will make an aural-only game for the Shuffle crowd? If done well, would be a neat trick.
Hm. I wonder: add up the total number of 5G units that Apple has sold. How does this number compare with the DS and PSP?
Someone apparently made an aural game for the GBA... Sound Voyager, part of the "bit Generations" line. I haven't seen it myself, but apparently the only visual bits are just so that you can learn what you need to do.
