Thinking about games that I've still never played!

Whilst enjoying the closure of my school today I had a quick look through the games cupboard and thought I'd have another rook at FFG's Horus Heresy as I bought it a long while ago but have still never managed to get it onto the table (the cards are still in their wrappers!). This got me wondering if anyone else has any games in their collection they still haven't played? How old is your oldest unplayed game? Come to think of it I have an old Lord of The Rings Reiner Knizia game from around 1999/2000 which I'm sure I've never played with anyone (gave it a go solo as it's a co-op, but that was last millennium!).
