Great games you own but don't like or never even installed

[caravel]

Thief II - Never actually installed. I got burnt out on Thief (which is a good game but some of the later levels get too frustrating) and decided not to take it further.

Morrowind - Walking and walking and walking, then running up to someone and rapping on the keys as fast as possible in what is apparently referred to as "combat". Then talking and clicking through line after line of pointless dialogue wondering if I should be remembering any of it.

System Shock 2 - Wandering about aimlessly with weapons that break after three or four uses etc. (yes I know it's a classic but this game depressed me.)

Medieval 2: Total War - For me this was the worst TW game so far. RTW was bad enough but this thing has so little to redeem it. I've not played ETW and probably won't now. I probably played M2TW two or three times before uninstalling it and throwing it on the shelf.

Unreal Tournament III - For some reason I've never felt inspired to take this out of the box. It seems like it might be UT2K4 with a makeover and I don't play FPS much anymore anyway (I picked this up in the 'bargain bin').
