Maybe a driving game that you could steer a virtual steering wheel with your thumb and maybe have two small pedal on one side of the screen for gas/brake with your other thumb, well, maybe that's going a bit far...
To be honest, I'd like to see Java implemented on the iPhone since one gaming site I go to uses it, Pogo. It'd be nice for when I'm on the bus, something I realized the last couple times I've gone out this week. Pinball would be nice as well as a DOS emulator if this is at all possible.
Yea, I hope they add this in at some time also, I'd love to be able to get on flash enabled sites or java supported and play online games...
I'd be happy with some popular PDA games such as,:
"cut n' paste"
"Where am I?" (Made famous by Garmin and Magellan)
"Swap the battery"
"Super 3G downloading"
"Adventures with Drag and Drop"
....and the ever popular paste time, "Save as"
how about "Safari Flash"
Capcoms "file browser"
and of couse the ever popular
Atari's "mms messaging"
