Of course I won't believe this until Microsoft releases an official statement, but it sure is intriguing, and would make it so I don't have to get an original Xbox to play GOTY.
Why the blighters, would Microsoft invest in making it compatible?
They serve PC-support packages, where this game can be played, and probably, not sure, PC-gamers are a dominant market factor....
Of course, the Nintendo, Sony - and others - have had their market place/share, deserved and well, or not, for the development in competition of PC-playable games.....
Many tried....but.....
In the end, there can only be one!
