If you don't know what Spore is, well, it's time you found out about it. Seeing it end to end for the first time can be a religious experience. But given that people might have various levels of interest, I'll give you some choices:
- Original full presentation - The hour long GDC 2005 talk by Will Wright. If you're a geek like me, you'll appreciate the whole back story and all the commentary on procedural methodology.
- Original demo - The half hour demo portion from the above 2005 presentation
- Gameplay clips - Three minute reel from GDC 2007
- Flash Movie - Only like a minute long, but does a surprisingly good job of summing up what the game is all about
