Okay, so sorry if I should know the answer, but I don't know and I NEED to know. The store page for this game, DOOM 3 (and not DOOM 3 BFG) says that it is not compatible with Vista or 7, only 2000, ME, and XP. Now, I know this is not true; I've seen people play it on Win7 systems. I would like to know if it really works or not, and what it means by that it's not compatible (faulty saves? startup probs? etc.; what are the exact problems, if any). Also, if I can run this on Windows 8, I would like to know if I need anything special like a program or mod or whatever to run it, or if I can run this as is.
I really want this game; I'm a big fan of the series and I've played the other games. I just want to know if I can get it and be assured that it will run with little to no problems on my PC. And no, I won't get BFG edition because, long story short, this version is more accustomed to my needs and preferences.
Any help at all to answering my questions would be appreciated. Thanks in advance to all who answer.
