The Galaxy on Fire space trading sim has been available on a wide range of mobile phones for a couple of years now. Just recently, a version with upgraded graphics and motion sensor controls was released for the iPhone and iTouch. PC World ran a piece on it:
I forget how many space sorties I've flown over the years. Elite, Privateer, Wing Commander, X-Wing vs. Tie-Fighter, Freelancer....but those days are long gone. Then I saw Galaxy on Fire 3D for the iPhone, and all those memories came racing back.
Here's a title with a pretty impressive 3D engine-for a cell phone game. I hate to have to even throw in that qualifier, but hey, I want to point out that I'm playing a game that looks on par with the last Wing Commander games - in the palm of my hand.
