What are the best games you've played on PC from all time?

Dark Forces, and most of the recent ones I loved to play.
Just interested what others think. I have a PC capable of latest mission playing online games and seems to be able to run most any game again at least exclusive speed, I'd love some ideas for some of the best PC Games Series I just know I'm forgetting.

I'm a huge fan of the old System Shock games, those are great fun, and I also love the classic Civilization games, they're a lot of fun to play!

Mario Kart for Mac hands down for me personally.
