Just curious as to whether people have had similar seriously disappointing gaming moments such as discovering a level you just simply could not surpass, or a technical glitch that prevented you from finishing the game or possibly even a game you started out really enjoying that fell flat on its face and had you saying to yourself, "What was I thinking??"
Here are my most memorable ones:
-- Playing Novalogic's Black Hawk Down online and becoming a holy terror as a sniper, then taking a haitus and coming back months later to find virtually every server being taken over by hackers.
-- Getting 60 plus hours into S.T.A.L.K.E.R. and pretty much seeing the end in view, and forgetting to save and the only Autosave being a retarded save that put me in harm's way the moment I reloaded it. I was so angry I uninstalled the game.
-- Being an avid fan of Sid Meier's Railroads! and installing it on my new Vista system and suffering a CTD once every 20 minutes.
-- The fact that I have NEVER won an online skirmish in Company of Heroes. ugh! (Still this is the ONE game I can still suffer defeat and have a blast doing so.)
-- Subscribing to Computer Games Magazine, Games For Windows, and PC Gamer and watching CGM and GFW fall by the wayside. I lived for finding these in my mailbox.
-- Buying an Xbox 360 controller just to play Indigo Prophecy, and discovering a bug that wouldn't allow it to work properly, and getting NO support from Atari.
-- XP debt in City of Heroes. I played through whole levels with XP debt weighing me down like a grand piano on my back.

10 minutes into Deus Ex: Invisible War and finding it nothing like it's predecessor.

Playing Spore...

Playing Oblivion and discovered it sucked.
Playing Bioshock and discovering it was a very pretty but mediocre game.
Starting a game in NetHack, finding gloves in the very first room and discovering that after putting them on, they are gauntlets of strenght, very useful for my valkyrie as it boosts strenght to the maximum. And then falling into a spiked pit as I tried to exit this very first room. Game over.

C&C Generals: the only game that spent less than a day installed on my computer, worst au$80 I ever spent. Dumped it as soon as I realised I could finish one of the missions with literally 2 clicks, pathetic shit.
Far Cry: I'd have to rank the supermutant plot as one of the biggest disappointments, completely ruined the game for me
Dawn Of War Soulstorm: Incredibly samey and dull, big letdown.
Monkey Island 4: Monkey Kombat, 'nuff said

Doom 3 because it destroyed the name.
Gothic 3 because it was unplayable.
Hellgate: London because of how bugged it was despite the hype campaign around it.
Oblivion simply because not only did it not deliver on any of its promises but the voice actors were beyond horrible since it was the same 4 or 5 people...

Ah, a thread to my liking.
Oblivion - discovering how fucking shitty that game really was beyond maybe the first two hours. Being outraged over the months I'd spent in hypeville and anticipationtown. Cursing Bethesda for all eternity.
Fallout 3 - CTD every 10 minutes. No support from Bethesda. Nothing I've tried could ever make the game work. Also the "intro ending" in the vault sucked, which is about as far as I bothered to get in that particular buggy piece of crap. Cursing Bethesda for all eternity and in any parallell universes as well.
NHL 09 PC - discovering it was nothing like the sleek PS3 version, oh no, it was a sloppy shitty cocksucky PS2 port. Cursing EA for all eternity.
Mass Effect - discovering it was pretty crap, the filmgrain shit pissed me off, as did the repetitive stale uninteresting gameplay. Cursing BioWare for at least 5 years.
FEAR: Any expansion - generateRandomLevel();
Gothic 3 - this unpolished piece of utter semen-stained smegma garbage ruined the Gothic series, including making the series completely uninteresting for anyone who had not played the previous games. For those who had, the agony was even worse.
Neverwinter Nights - discovering this, the most massively hyped RPG on this side of the last hitherto unknown advanced ancient civilization, was a linear mumbo-jumbo lined with steaming piles of shit. Cursing BioWare for 5 years.
Age of Conan - disovering FunCom had released a game which was about as finished as a frozen pizza. When it's still in the box. In the freezer. At the store.
Empire Earth III - discovering the developers managed to fuck up one of the greatest game series ever by removing everything that was good about the previous games.
And last but not least;
MONKEY KOMBAT.

Tony Hawk's Project 8- I've been giving the Tony Hawk series an undeserved amount of attention after THUG and imagine my surprise when I was crapped all over with its lack of create-a-skater and create-a-"anything that made tony hawk awesome" modes.
Guitar Hero games after 2- Neversoft just not quite "getting it"
Don't Shit Your Pants - Shitting my pants..... posthumously.

Hell yeah, Neverwinter Nights. That one was a major disapointment.
One year later I played Arcanum for the first time and was so happy I almost cried.

Ditto on Empire Earth 3. Travesty. God EE was a great RTS game.
Ditto, Oblivion. I honestly think it's an excellent game in its own right, but it can never hold a candle to Morrowind.
Call of Cthulhu is one of my biggest. Opening was great. Certain sequences were great, but it was just outrageously hard, loaded with incredibly tough stealth and shooting sequences complete w/respawning enemies (the warehouse also had too many level puzzles) and it got buggy and impossible to play near the end with the boudlers. I think that honestly could have been the greatest horror game ever made with a few more months of playtesting. As it stands, probably the most uneven game I've ever played and one of the most frustrating.
Final Fantasy XII. 20 minutes in when the first battle happened, I was like WTF - when did FF become an offline MMO?
Clock Tower 3 endboss. Just broken hard..
Eh, I like NWN. HotU is legitimately great. OC isn't amazing, but it isn't as bad as everyone says either. Pretty competent RPG even if it wasn't BG2.
I loved SS2. I bought SS1 after playing 2. I hated it, violently.

Spore, hands down. Followed the game for years, watched every video about it, worshiped Will Wright, preordered the game (first game for me to do this), arrived at the video game store early the day it came out (even though there was no line), brought it back home, installed it, played it for a day, then sold it to my friend. To this day, I feel guilty for selling him such a piece of shit.

I have a feeling my most disappointing moment is in the future when my new faction leader murders my awesome racial leader, if rumors are true.
Until then, I'll go with Deus Ex: Invisible War. The whole game.

I found Scrapland pretty disappointing. I bought it because I really enjoyed Alice. I ended up only playing it for a few hours, as it just seemed very pedestrian. Maybe it gets better later on, but I doubt it. After it was released, I never heard anyone mention it ever again.

FEAR
game praised and loved by many...
i found it tedious and incredibly boring with its unending repetitiveness, unoriginal weapons and enemies, bland surroundings and cliche moments.
