What system did you never get to play even though you wanted to?

Since 3E ended, I've actually managed to try out several games that have been sitting unplayed on my shelves for years. Still hoping for the chance to play:

Call of Cthulhu
Dark Heresy/Rogue Trader/Deathwatch
Fading Suns
Fireborn
GURPS
Mutants & Masterminds
Rifts (though with a ruleset I like)
Space 1889
Twilight 2000
WHFRPG (2E & 3E)

and I want to do another game of Paranoia

Of games that I actually own and have never played only Mutants and Masterminds comes to mind. If I buy the rulebook for a game I darn well play it!

As far games i neither own nor have played (but want to)

Star Trek (any as long as it is set in the original series' time line)
7th Sea
Dresden Files

Nothing else comes to mind right now.
