And Sahil, the list of games in the poll is extremely restricted. It might be better to get the opinion of people in this thread and then make it a poll....
I am still in love with Baldur's Gate, Baldur's Gate 2 and Neverwinter Nights. The two Baldur's Gate games have a very compelling story and awesome gameplay. The aging graphics don't even enter the equation.
My favorite PC Game is Pro Evolution Soccer 6. It's a great game...because i love football. I like also Football Manager 2007....a beautiful manager game!!! Fifa 07 is good but. for me...Konami is better than EASports!!!
I used to be addicted to Heroes of Might & Magic and the Civilization series of strategy games. No time for games these days though.
Gotta give it up to CS, it's been going strong for so long now. Not to say pacman hasn't, but umm... counter-strike is just so competetive it's hard to get tired of for me.
I have stopped playing PC games for a long time. But I used to play Age of Empires which was an extremely entertaining game. Westoff.
