Games you never uninstall/eventually reinstall

[PsykoDragon]

Tell me what games you have that you haven't ever uninstalled/always eventually reinstall due to replay value/it's a fun game/it's worth keeping. Small-scale & indie games included.

My list:
Burnout Paradise City
Melty Blood Act Cadenza
Upshift Strike Racer
Brainpipe
ROM CHECK FAILURE
Veck
Sid Meier's Pirates!

Hm...Mostly I just unistall and keep them off nowadays, but earlier on I used to dust off old favorites, examples:
Empire Earth
Age of Empires 2
Roller Coaster Tycoon [The first one]
Emperor: Rise of the Middle Kingdom

Oh god damn...now I want to play that last one...but I lost the CD key years ago...T-T

 

[Zani]

Rome: Total War
Medieval II: Total War
Empire: Total War (I really like the Total War series )
And at least one STALKER game.

warcraft 3 is just about always on my HDD. that, and I lost the cd key so if I ever have to reinstall it i'm boned.

 

[MiracleOfSound]

Fallout 3

Never leaves my hard drive, as it's my go-to game when I need some calming down or relaxation

 

[Johnnyallstar]

Angband has been on every one of my computers in one way or another.

 

[CoverYourHead]

Warcraft III, Diablo, and World of Warcraft (mostly because reinstalling it and downloading all the patches again would take me several million days).

 

[Cuacuani]

Deus Ex and Vampire: the Masquerade - Bloodlines always end up on my computer eventually.

I haven't uninstalled anything yet, but if I had to decide, it'd be Oblivion, Audiosurf, and Left 4 Dead. They're all amazing.
