Oh gosh, I can't really remember, but I'm sure it was 2004... Let me think... I'm pretty sure it was either at the end of november or beginning of december since I remember playing morrowind during christmas-preparations and dreaming about the sequel.

So I guess it's one year and three months?

It surelly feels like more...
