I played this again last year for the first time in about 8 years, the original the disk worked fine on Vista. I originally played it purely as an FPS. This time. I played it with the advantage of many more years of gaming experience and it was a totally new game so many of the scenarios worked out differently a good replayability factor. The graphics are a little old but you forget that as you become immersed within the story. Highly recommended.
