Most disappointing game ending ever?

Just finished PoP-TFS. 
 
A lot of reports I saw on this game considered it lacking. I concur, but I don't think it was terrible game. Me and the Mrs have played every PoP game in this series together along with that other awful incarnation a fews years ago where you weren't allowed to die. She loves Warrior Within the most and I will never forget my first play through of Sands of Time as a teenager, because it blew my mind. TFS feels like it fits into the series well in terms of its theme and story, I think the main issue with it is that it is 2010, not 2001. If this game was the second game in the series and made back then I think it would be a much more revered title. The fact that by todays standards it isn't a great game is more of a testament to how much platform games and peoples expectations in game quality have evolved as opposed to the actual quality of this game. 
 
I don't want to ruin anything for anyone who hasn't played the game, but I have to say the end sequence was really quite extraordinary. It looks FANTASTIC and had a stunning pace to it. The ending was nothing to write home about, but the build up to it was quite brilliant to the point where I found myself thinking; this is what PoP games are all about. It was far better than the endings of some more recent games and when the lady asked what I thought the worst ending to game was ever, in terms of sequence, layout and enjoyability it sparked me thinking. But only for a very short while, because in truth I picked my least favourite game finale a long, long time ago. For me, it is without a doubt God of War 2. It was clunky, dull, frustrating and annoying. It was also disappointing and pointless. It lent on the fact another game would follow it and it was just pathetic, it really should have just ended with the battle with the sisters, which was great. Instead, it just got ridiculous. 
 
So my question to you lovely folk is: what is your least favourite end to a game ever? (This isn't in regards to the story of the game, but the gameplay/final boss, etc.)

Bioshock.

Fallout 3

dark cloud

Assassin's Creed.

Infamous, there was just something missing there and I can't quite put my finger on it.

Halo 2. 

Of recent memory? Probably Dead Space

I agree with most posted thus far, most notably Assassins Creed. Just another reason to add why I despise that game so much =/. 
 
Another that always comes to mind is Psi-Ops. It cuts off as if a sequel was in mind; shame it never came to be.

Bioshock.  The last third of that game was just no good. 

Near the end, Bioshock got extremely dull for me and I stopped playing. I later saw my little brother complete it and I don't have many regrets. Ending he got looked terrible and I don't imagine the others being much better.
 
It wasn't bad, but I was a little disappointed by Red Dead Redemption's ending at first. It took a while for me to appreciate it but my first impression was "that's it?".

assassins creed II

" assassins creed II "

Fable II

Resident Evil 5. It felt like they realized the story was so stupid they tried to wrap it all up in one game.

Wha??? I thought that ending was great, gave a good conclusion of that story while teasing and showing alot on the potenial of the franchise "

Bioshock.

Red Dead fizzled out soobadly after the killing of Dutch. Yes. We get it, these are no times for outlaws, your days are gone etc.
 
I can SEE what they were going for. John settling into the life he tried to carve for himself and the development of the relationships between him and his family members.  
 
It all fell flat though. The missions were tiresome, but moreso, the very fact that (after trying to highlight the fact that his son was to make something of himself in this changing world) he goes on to become EXACTLY LIKE JOHN.
 
Fuck RDR. I enjoyed a lot of it, but the writing was awful, the story was fairly poor (not so much in the grander scheme of things, but how we got taken there) and the characters absolutely despicable. The most interesting thing about the whole game was the "stranger" side-quest.
 
Edit: I started with the intention of just slating the ending and then things got out of hand...

Mass Effect 2. I just thought it was dumb.

Sudeki.  You beat the final boss, get a 10 second puppet show, and credits.

I thought the ending of Mirror's Edge was pretty lame.
 
I was just left with a feeling of "That's IT!?"

Probably Assassin's Creed.

The ending of Fallout 3 was really really bad, but it wasn't very disappointing since the entire main storyline sucked ass. 
 
I would say the first Diablo. After battling through hell itself and finally slaying Diablo your main character impales himself with a soulstone which effectively makes him the new host of the demon. It truly felt like everything you did was for nothing.

Parts of the Final Fantasy XIII ending kinda pissed me off, while others came off as pretty good and well thought out.

Alot of hate on RDR. I really liked the ending, was probably one of my all time favs. 
 
The halo 2 ending sucked so much ass, me and my friend blazed through it on co-op, and to end it as the climax was about to take place..... man I was so pissed off. 

Fallout 3

Borderlands. I spent dozens of hours on Pandora just to fight a giant mouth thing what the fuck!!!!

Big rigs.

Starcraft 2. I hate Kerrigan i wanted her dead.

I'm surprised no one has said Fable II yet.

" Halo 2.  "

I'm surprised no one has mentioned KOTOR 2. That pissed me off and made me never play that game again. I realize its not Obsidian's fault since they had development time cut but still it was just terrible.

God of War 3. I was actually stuck for a long time and didn't pick it up again until recently. When I did, it was only to find that I was 10 mins from the end.

" Resident Evil 5. It felt like they realized the story was so stupid they tried to wrap it all up in one game. "

KotOR 2

Still don't know why they connected RE4 with everything in this series during RE5!!  I really liked the idea of RE4 was a new start.  RE5 was good fun for the co-op but trying to stitch up every little thing in RE series was a big mistake, it got to the point I didn't even care when I found something I had to read.  RE4 and RE5 should have been a new story, no umbrella corporation needed. "

While I can agree Fallout 3 and Bioshock both have short and dissapointing endings what immediatley came to mind was Gears of War 2. I liked the ending to the original Gears and it made me want to see what happens next, the war intensified in the sequel but it had a lame, weak boss and an ending so lacking.

Metal Gear Solid 2 & 4. To be honest I only played MGS4 in the name of justifying my purchase of the PS3 which wasn't until games like Demon Souls and Ninja Gaiden Sigma II finally arrived to redeem my investment. lol
