One thing to note is that this won't be able to go into the Itunes App store. There are licensing issues involved, first from the use of the Microprose media assets, but second, because open source projects, at least GPL, are generally not accepted by Apple. OpenTTD (Transport Tycoon) ran into this, even though all the graphics and code were original. It was up for a brief time, but then pulled down and not allowed back.
