Games you haven´t finished.

[SirFrog]

Do you have any games that you by some reason not have finished?
Any game where you´re stuck and can´t get trough?

Edit: Somehow, i was expecting to hear about the games who you have not gotten through the main storyline, not the games where you have not collected everything there is.
(in that case, my list would be infinite...)
Examples:
Super Mario 64: Defeated last boss, not gotten all stars. [Status=Beaten]
Pokemon (Anything really, but let´s say the ordinary red) Defeated all of the Elite Four, but not the last one. Have all Pokemon [Status=Not beaten]
(I just have to brag here, i have ALL Pokemon possible to get in Red, Nr 151 Mew included. I do not however have the Pokemons from Blue, none of my friends had a Gameboy.)

My list:
Legend of Zelda (stuck in last dungeon.)
The Incredibles Videogame (Too boring...)
Warcraft III (In orc campain, have played other stuff...)
Donkey Kong Country GBC version (Always die in the third world...)
Mario & Luigi: Partners in time (always die on the last boss...)
Final Fantasy III (Same as above:confused

oh, remebered a new one!
Final Fantasy: Crystal Chronicles for NGC. (It was too boring.)

[Scorpion]

Harvest Moon: Innocent life (too boring)
GTA Vice City Stories (too much to do, i used a savegame)
Juiced 2 : HIN (too boring, again used a savegame)
COD : Roads To Victory (i can finish it but anyhow i didn't feel like finish it )

[Silverthorn]

Tetris for Gameboy (neither getting to lvl. 20 nor maxing out the score :P) [wow, I haven't played that for ages!]
any Pokemon game (because I'm too lazy to catch them all :P)
playing every Rockband song with any controller on expert (because some songs are just hard like heck + not enough time)

[Lauli]

LEGO Rock Raiders :/

Yes that's really the only game I've never ever finished in some way.
