Well, it would be pretty neat anyways. The concept of train simulations on consoles hasn't really gone further a few Japanese High Speed Train Simulators. It would be something around the TRS2004 area if I took a guess. For the saving, there could be a special PS2 Memory card with more storage. Developing a PS2 game would be pretty easy if you know what you are doing. I mean, look at what is out on the Xbox 360 and PS3. Its a shame PS2 games have been discontinued.
Oh yea! Shane, have you tried getting on with N3V? You know your stuff!
