Since you liked halflife maybe you might like the
3rd additionStar craft 2Top PC Games of GamespotCNET Best PC GamesI use to play quite a bit, then my son took over the gaming.
Now neither of us play that much.
But, when "I" did, I loved the Need For Speed Underground Series 1 & 2
And some Shooter Games.
Now, my son is more into Football and WWF and Shooter Games.
My favorite PC Game of all time is in Order:
KISS Psycho Circus (Big KISS Fan, so I love this game)
Doom 3 (Cannot wait until DOOM 4 is released)
Quake 4 (There is an Online game that is FREE as well that is back to the original concept of
Quake Live )
That is about all that I can think of right now.
Good Luck and have fun in your choice of distraction.
