Games which you dislike, or did not live up to expectations and such.

Rochard
Microvolts
Bunch of Heroes
Bunny must Die! (painfully bad)
Terraria (hated it)
Wizorb

Pariah (disappointed me)
Fort Zombie (do not play)
Space Marine (I got bored while playing)
Dota (LoL all the way)
Last Survivor (too much fake difficulty)
Starcraft 2: WoL (this game wasn't "bad" but it didn't live up to the original in my eyes)
WoW (I got bored, although that's probably because I didn't play with my friends)
Star Trek: Bridge Commander (I said "intercept course" not "RAM DEM WIF ARE SHIP YO!!!!" That's a "collision course".)
Halo: ODST (I didn't like the whole "You don't have shields, BUT you do have this sort of regenerating health buffer....")
Brink (The singleplayer AI... screw you developers. I've literally gotten a 100 k/d and my team still lost).

Maybe more if I think of them.

Super Smash Bros. Brawl.

Nintendo.

The Wii (No HD, game lineup is crap, sub-average motion controls)
Halo: ODST (same reasons as Sniper)
Brink (Good idea, bad execution, coupled with what Sniper said)

Aeon.

Uncharted 3: It was like the first 2 games with just a different (and forgettable) story. No new interesting mechanics. Overall unnecessary..
Bioshock 2: I guess so. I don't really know since I just never had the motivation to complete it. I only got to the second area before I lost any sort of drive to play it. Once again it felt completely unnessecery.
InFamous 2: Story a combo of cliche, lame, and stupidity (Seriously why would they destroy the city you spend the entire first game on fixing, lol? *not spoiler because it's in the trailer*), IMO. New mechanics were introduced, but I thought they were annoying and forced more than anything else.

I guess I have some beef against sequels, lol. I don't come across many "sour grapes". Because most console games are pretty expensive, I only get the ones I know I will enjoy to some degree or wait obscene amounts of time and get cheap games that were popular in past years. (I will get Portal this year! I mean it!)  

Portal was a good game .

Portal 2 added some interesting mechanics, but really is just more of the same. A LOT more. I enjoyed it, played it a few times and searched for secrets etc, but you might not if you don't like story extensions, which is basically what it was.

Sniper, you missed your 1000th post! How could you!!!

I think that Portal Uno had a much higher replayability.  Maybe it's because it was my first FPS game that I'd owned, and my first major PC game, and so it holds a greater meaning to it, but I find it much more fun.

First Person Solver? ;p  

Agreed, although I'm also not sure if it was just because it was the first time we got to dive into the wonderful world of portals, but I know I replayed it a few dozen times, which is easy because it's so short. Portal 2 definitely had its moments though. "How are you holding up? Because I'M A POTATO."

When I look at it, I see Portal as the solid portal game: You play with portals and that's it.  Oh, maybe an innocent little turret here, and an incinerated Companion Cube there, but there's not many mechanics other than simply using your gun.
Portal 2 was a deeper story line, answering all (most) of your questions, but added so many more mechanics that altered the game all together, like the gels.  It had the best humor, but it almost took away from the core of the portal gameplay.
That's kind of a super-simplified version of what I think because I can't quite put it into words, but at least we're on the same level.
"Sarcasm self-test complete"

How long is the list allowed to be?


All call of dutys from the 5th
Heroes of newearth
Duke nukem foreever
Battlefield 3
vvvvvvvv (Yes this is a game)
wizorb
uplink
Diablo 3
cogs
And yet it moves
Breath of death VII
Fieldrunners


The blockbusters  in there are bad since they are poorly optimsed and buggy
The indie ones and bad since they did not come with good gameplay and had clunky mechanics

I'm curious as to why you think BattleField 3 is bad.  Explain?

Crashing, i can play a game then it crashes. It have been so since the release
Pay to skip everything (Also called "starter pack"... You basicly get all unlocks), "Premium" aka pay to get onto servers faster than normal people (you get into the line before the people that havent bought premium even if they have stood in the line to join the server for 5 hours).
EAs support basicly told me to change GPU since it was not the card that was on the box (You know if you read on a game, and it says minimum hardware and recomended hardware) to a 6950 (A good card no doubt) from a 7970 (This is the best single GPU on the market for most things).
No mod support! (they said it should have it later down the line)
A tool that changed the colours was classed as a hacking tool and lead to a permanent ban
The game is made through a blue filter (Blue is the main colour)

Problems people might not agree with...
vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv

The sun is too bright
Poor game mechanics
Very poor balance

Oh yeah the sun glare is blinding
