Edit: This post of mine is to verify whether or not the game requires a later OS. But I don't believe that's necessary since it's only an upgraded version of the original. id Tech engines are renowned by me for their compatibility. And nobody needs to get worked up over what OS's they use. Operating systems are tools, not toys. (Though we kind-a use them for that). Keep it clean here.
Some can afford to upgrade some can't. My reasons for sticking with my system is because I cannot really afford to buy new licenses every few years with fresh hardware, but I can save up just enough for a nice little game to play sometime. I've been into the Doom series for a long while, so, just bare with me on common tastes in what games we like, again we don't need to get political about what OS we run. I just want to know if I will be able to run it on my current system. Windows XP Professional 64bit. (Got it for a discount, works better than my previous attempts with vista, and 7 trial versions. Unless we all own identical brand built PC's, things will work differently for everyone.)
