I don't remember the exact wording, but it was something like, "if you strongly desire something, by the time you get it, you might not need it anymore." Something along those lines.
So, I wanted to play the second Knights of the Old Republic for so long, and... now that I have it, now that I've launched it (and, of course, it runs without any glitches), after fifteen minutes of playing, I turned it off, not getting any enjoyment from it, and haven't turned it on since.
By the way, I expected more from S.T.A.L.K.E.R. I didn't like it, just like I didn't like Neverwinter Nights. %)
(Generally, they are good games, but still...)
P.S. I've already finished the fourth GTA. If we're talking about difficulty, out of all the ones I've played (GTA 3, GTA VC, GTA SA), this one is the easiest. And the most difficult is probably San Andreas. Just remember the mission where you have to jump from one plane to another.
