Even though Windows NT 4.0 was mainly on business and school systems, you could still play all those 3D FPS games with a good graphics card. Not as common as gaming on Windows 95 but some people *cough* *cough* would play those games at work, and Windows NT 4.0 with all the service packs installed was pretty darn good and was the same base code as Windows 2000 and XP.
