Halo 1, 2, and 3 - All huge disappointments to me. They just weren't fun... Yeah, the coop single player is a great feature that I think all FPS should have (come on, even DOOM had it, why isn't this a common feature?)
Oblivion - An awesome game, but a little disappointing because the main storyline was so short. Also, a lot of the content was just fluff. The QUESTS weren't fluff, those were great! The random dungeons, caves, ruins, etc. in the countryside were 95% fluff. Some people like finding random dungeons in the wilderness and walking around inside of them without any reason. I don't. I want purpose behind me adventuring, not just killing monsters and finding loot. I hope Fallout 3 doesn't suffer this fate...
Vampire the Masquerade - Bloodlines. It's buggy as hell and crashes constantly on both of my computers (one is a A64 3200+ x800XL, the other is A64 X2 6400+ 8800GTS). I got through the entire first area (Santa Monica) before giving up with the bugs and uninstalling. NOTE: I had all of the official patches and tried both of the main unofficial patches just last week. Any game that I can't play on a fairly standard system is not a game. From what I've read, those people who do have it running smoothly still have to put up with tons of bugs that aren't completely fixed yet even after years of community development, and that's bullshit. It could have been a great game, but I'm not going to support a product that was ultimately unfinished - doing so tells game producers that it's an acceptable practice.
Black and White (and Black and White 2) - I just couldn't get into it. The game mechanics were frustrating at best (figuring out exactly the right way to throw things was a huge pain in the ass).
Call of Duty (all of the games in the entire series, the only one I didn't try was COD3, and by 'try' I mean 'borrow the disc from a friend') - I just couldn't get into them.
World of Warcraft - The end-game is bullshit. I started playing immediately after Burning Crusade was released. The first 10 levels went by in a flash. Levels 10-20 were awesome! I was having a great time. Levels 20-30 slowed down a little, but still very very cool! Levels 30-39... can't wait to get that mount, by now a lot of your quests have you going all over the world, so the slow foot speed (I played a few different classes with skills or abilities that helped this, such as the Druid travel form) is a huge detriment until 40. Levels 40-50... okay, now that I have a mount, my traveling is a lot faster and the game is more fun again! Levels 50-60... WTF are all of these factions? Why do I need to kill 1000 fubolgs just to reach Winterspring? It's so excessive! By this point in the game, you see that a lot of the end of game content was designed to waste your time. A lot of the factions would require tens of thousands of "reputation points" and most kills would only give you 1-2 reputation... with maybe 50-100 points here and there for certain quests or collected items.
Levels 58-70 in Outland were exciting, all of the content there is pretty cool until you hit 70. At that point, your life is probably being spent grinding gold, PvPing or raiding. There's no longer anything to do except try to get the best loot. Some of the raid content is pretty cool, but a lot of it is unnecessary and kind of frustrating. I think 5-man instances and 10-man raids are the perfect numbers. I could see 15 being pretty fun. 25 is excessive, and the whole thing just gets to be frustrating. Unfortunately, all MMORPG developers have a fetish for frustrating their high-level player base. Also, class balance is pretty broken in raids. It's impossible to beat a good warlock in DPS (basically mages are useless), and for awhile paladins were hands down the best healers of any class (until the illumination nerf, at which point we were still uber it was just less obvious). I quit right before the Zul'Aman patch and might return for Wrath of the Lich King, but will create a character from scratch.
I don't understand how anyone could be disappointed with Bioshock... it's a rehash of System Shock 2! You've got a fantastic storyline in an incredible environment (it was good graphically even if it didn't blow your mind). You get lots of cool weapons AND psychic powers. What's not to love about that? The hacking was bland, but it's optional and with enough research you don't have to play that hacking game anymore anyway
