Is it possible to run Gran Torismo 5 on the Xbox? As you know, I have an Xbox system, and I own a 2001 Honda Insight. I've noticed that the Insight is available in Gran Torismo 5. I was hoping it was also available in Forza 3, but have not found it yet. I wonder if it's in one of those packages you have to buy on-live. I'd hate to buy a Play Station system just for that one game and just for that one car. Is it remotely possible to run a Sony game on a Microsoft system?
