What games did you start but never finished?

I've been trying to complete the bioshock series for awhile. Also I started half-life 2 but I doubt I'll ever finish it.

Assassin's Creed Brotherhood - I didn't like the story.
Kingdoms of Amalur: Reckoning - The story is very cool, but the game is way too easy and the bugs ruined it for me.

There have only been a few games I've stopped and haven't gone back to complete. One is Jericho. Another one - and I'll probably get flogged for this - is Assassin's Creed. I felt pretty bad about it too because I wanted to like it, and the story seemed interesting, but I couldn't get into the gameplay. I did enjoy Brotherhood's online multiplayer though.
I do see myself possibly going back to finish both at some point, but it's not a priority for me.

Penumbra: Black Plague is a lot better than Overture. You should definitely finish the first and try it out.

I can't start nor finish Skyrim. Though I finished the prologue, the next day I can't even touch it again. I don't know if there's a disorder regarding this.. Gamer's Block?

I forgot to mention Modern Warfare 3 too. I feel sorry not only for an unfinished business, but double posting as well. Apologies.

I didn't finish GTA:SA, just couldn't get past that one with the biker. Lol

Bioshock, Diablo 3, Return to Castle Wolfenstein are some that come to mind. Starcraft Broodwar, C&C Tiberium Sun, Dawn of War series (just played multiplayer in that), Total Annihilation, HL series. Currently still playing Skyrim...

Whatever game I don't finish I watch the story on youtube It's just easier to watch it if you dont have time to play but have time when commuting or at work

I did it for F.E.A.R. 1 & 2, Max Payne 1 & 2, Halo 2.

These are just games you have to know the story, same with other titles you guys are listing. Reminded me of other games I need to watch.

Every GTA except III. Always hit something hard and find it more fun to rampage (plus I just didn't like Vice City).

Both Batman games. Always hit something hard in that "you have to be console-twitchy and reload 20 times" way, and find it more fun to quit.

Crysis. I didn't like it.

But in general, I'm a finisher. I used to not buy a new game until I finished the current one.

Forgot "Fury of the Furries". Great game! Pity the old Amiga was so slow it made it very time consuming to play.

LNCPapa that is a HUGE list lol...damn

from all those games you have to finish Mass Effect please finish it lol

Never really thought about it, but I have a surprisingly long list:

Amnesia: Dark Decent - BF3 took over my life right after I started it
Dead Space 2 - Got too low on ammo and couldn't get passed a certain part
F.E.A.R. 2 - Got repetitive
Half-Life 2 - For some reason the game crashed at a certain point so I couldn't play further
S.T.A.L.K.E.R. - Bought it because I thought it was supposed to be scary, wasn't
MW3 - Did the single player, but I dont think you've really beat the game until you've prestiged at least once. It just wasn't that good of a game.

Never finished Skyrim or Deus Ex Human Revolution.

Final Fantasy IX.

I was playing as a 12 year old and because I loved VIII so much, I thought IX would be just as great. I got about half way through and got stuck in some sort of puzzle so just left the game and sold it. I keep meaning to buy it again to finish it properly though...

I'll list the ones I never finished because I lost interest:

Oblivion - main story too linear and Oblivion gates are annoying;
Fallout New Vegas - just became bored midway through;
STALKER - all three are just horrible. I bought them because they are loosely based on the iconic sci-fi book I read as a child.

The one I am sorry I finished: Mass Effect 3.

The one I am sad will never get a sequel: Masquerade Bloodlines.

The one one I am positively giddy will get a sequel: Witcher/Witcher 2.

one of the star wars games on ps2 where you play as jango. I think the most popular star was game was STAR WARS THE OLD REPUBLIC.

I've owned the entire Sam & Max series but I've only ever finished the first season. =\

I've also yet to complete Halo 3: ODST, even though I've had it for a while now.

Been so many over the years, but most recently... GT5 and Infamous on PS3, Deus Ex - HR, Star Wars - The Old Republic (I know it's not really finishable being an MMORPG but I said to myself I'd play one characters story through before cancelling but never did), I'm sure there are a heap more but I've found that the evolution of gaming into the online multiplayer/vs creature that it is now means for a lot of single player titles and "Story" modes of multiplayer titles I just can't seem to come back to them to continue.
