Well, the PC version that was originally under development wasn't exactly scrapped - they just changed it's target platform. Since the X-Box was an Intel based device with a specific set of specs, it was simply adapted to the X-Box (which probably didn't require many changes at all). When they decided it was time to put it out on the PC, they simply adapted the code again with little or no effort to improve on it. A true port might have stood a better chance if they were really interested in putting out a great game, but I think their real interest was simply in maximizing their profits from an old one. To me, that's the real reason it sucked.
