I'm talking about a full on game. Renderings of every NFL stadium, all the players, full stats. Everything that is on the console game version of Madden. Or Gran Turismo or final fantasy for that matter. For now let's set aside concerns about how it would be played, I am just talking about could a game that big work on the iPhone? Something that takes up 2G of memory and puts that much strain on the CPU. I can't really figure out if apps, while they will surely get better aren't going to change in a fundamental way, or if when devs really start to figure out the iPhone we'll see crazy things that we could never really imagine. For now I have a hard time playing aurora feint without crashing, so I'm leaning towards the former. In which case we'd never have to worry about disk space from an app. But if things like madden or gran turismo are possible, that's a different ball game.
