I too am a 'First person shooter' fan.
Last year I bought Halflife and the other three, only to find they would not work on XP.
Ebay however soon came up with a newer version of Halflife 1, blue shift and the others, which I have since loaded with no trouble.
I had Halflife2 for christmas, but not tried it yet, as its the DVD rom version, so until I get a dvd player I am snookered...
Happy new year to one and all.
