Games You've Never Finished

[Drunk Clown]

... that would be a really, really big list.

Resident Evil 4
Metroid Prime 1 & 2
Zelda: Twilight Princess
No Total war game (if I got to the point of feudal knights in M2TW, the fun was somewhat over, as you could steamroll everything without thinking)
Oblivion (did the guilds, not the main quest)
Fallout 3 (no time)
Splinter Cell: Chaos Theory
Half-Life (everything, do not like + motion sickness)
Titan Quest
Black & White 2 (gawd the repetitiveness),
Morrowind (started too late and now it's ugly and annoying)
San Andreas (dunno why was at big smoke)
GTA IV (due to helicopter bug in final mission(s))
Harvest Moon: A wonderful life (boring after you have everything)
Warcraft 3 (was young then)
SSX on Tour (repetitive)
Starfox Adventures (and don't want to)
Paper Mario: The thousand year door (dunno stopped before last boss)
Not a single Fire Emblem (got 5, and I find this most sad but every time I'm at the end of the game something new comes up, subsequently I want to start over again; a never ending cycle)
Super Mario Sunshine (When I was young I found it difficult, now I've not been that enthousiastic)
Tales of Symphonia (really sad, one of the best games ever)
Final Fantasy Crystal Chronicles (you need gameboys as controllers to play MP, which it's created for)
Baten Kaitos (them voices! the horror!)
Prince of Persia (Two Thrones + Warrior Within)
Advanced Wars: Blackhole Rising (shame)
Tenshu: Shadow assassins (wii sucks in this game)
Beyond Good and Evil (did not like,)
Final Fantasy IV (I'm at the last boss)

Hmmm can't think of more.

Strange is that I fully played Pokemon Channel twice, just to get Jirachi. And for those who don't know, Pokemon Channel is one of the most retarded and mindnumbing game there is.
Also I did manage to complete Assassin's Creed which is repetitive to the max and just a complete chore to play.
