Shadow of Chernobyl.
I bought the Collectors Edition. (In the nice tin box, with all the goodies!).
One of my top games!
Got the special "Cheat Mode" installed*, which works fine, gives me "everything", and enables me to go anywhere and do anything without the fear of dieing..... within the first few minutes!
I noticed that it required a very fast Graphics Card (with lots of graphics memory), and lots of experiments with different graphics drivers to get it to display correctly....and without crashing.
Personally, I like it.
It passes the time when I can't think of anything else to do, and I like the graphics, and sound effects...
