Anyways, the game's been available on PC for a long time. The requirements would've only mattered had this been a remake of some sorts, which it obviously isn't. As already mentioned, the re-release exists only because the earlier version isn't compatible with modern operating systems, and hence people had to run it via virtual Win 98 etc.
The stated specs seem more like a requirement to run Windows 7 reasonably well. Obviously, you aren't going to be able to run the game if you can't even run the OS properly
