Well, crap. I ranted to literally everybody that would listen that when Apple released the SDK for the iPhone, I wanted to make a port of
"Rogue" for the iPhone.
Well, someone else just did.
Gandreas Software just released a very faithful port for the iPhone, with some really innovative extra features, like the ability to pinch/zoom the graphics, switch from ASCII to graphics by tilting the iPhone, and including gesture-based commands as well.
It actually looks pretty cool.
