[PC] What is your Favorite PC game EVER?

Gotta have a list for this

Starcraft
Of course there were plenty of RTS titles prior to SC, but this has been my reigning favorite in the genre. It was just so much fun to play, and the online 'Use Map Settings' add-ons to the game were fantastic (for the most part). Even 10 years later, I have no problems picking it up and playing a quick match against the computer in big game hunters.

Civilization 2
Though I have loved the installments of 3 and 4 in this series to be just as pleasing, this one has a special place for me. It was the first one I played in the series (I have, however, since revisited the original), and it got me addicted about 5 minutes into it. It was the epitome of awesomeness at the time, and I am eagerly awaiting the next installment in the series, though I'm still busy with 4.

Diablo
Another Blizzard game makes it here you say? Diablo was the driving force that got me into MMO/Dungeon Crawler types of games. It was so simple, yet you just...couldn't...put...it...down. It was as fun and rewarding as it was addictive (thats assuming you played with your friends). Alas though, I haven't picked it up in ages.

The Elder Scrolls III : Morrowind
I actually got this after hearing some good reviews from my friends around the neighborhood. Needless to say, I was happy I picked it up. It was and still is a very deep experience in the RPG genre that you can spend hundreds of hours with.

SimCity
Goddamn, I remember playing this on my old P.O.S. Windows 95 computer. Such a great experience, and everyone has played one SimCity at one point in their lives. I never have gotten to the 1 million mark, anyone know how to?

How ya doing, buddy?
