If you feel nostalgic about PC games you've played 8+ years ago, visit www.abandonia.com
That site has a great collection of "abandonware" - old software (games) that have their copyrights expired and are available for free download.
I downloaded Colonization, Settlers II and now am enjoying a flashback into my early teenagerhood by playing Dune 2. Gosh, how primitive this game is, how unconvenient the controls (no grouping, no convenient right button) but it's still lots of fun !
