I'm one of twelve speedrunners of this game [1] and this is a killing blow to our community. Those of us lucky enough to have the game installed are the only ones who can continue speedrunning this game, and we can never uninstall it or switch computers. No new speedrunners can enter the scene. It was enough work getting it to run over the years without Games for Windows Live, or at a modern resolution, or at a modern framerate, with horrible keyboard controls, and without crashing at boot due to driver issues.
Now, new players can't even get their foot in the door enough to see that there are fixes. Even with a crack, this is the end of speedrunning for us.
