I suspect this is a big part of the decision. It certainly would be if I were making the call ... if the UX isn't perfect, you're going to get idiots giving it 1-star reviews and generally complaining. I'm not sure I'd want to release anything that didn't have a standalone/offline mode for the Touch, just because I suspect that users operate them out of range from WiFi much of the time. (Or at least I see users playing with them where there isn't Wifi pretty often.) Maybe someone will find an unofficial way of easily getting it onto the Touch ... that would make users who really know what they're doing happy, while also preventing the sort of people who are going to give it a 1-star rating when it doesn't work in the subway from installing it.
