Worst Bugs you had

When i was gaming I entered a place (i think it was in skyrim) the game crashed, and crashed after a while i stopped entering it after the update it was fixed
EDIT : and in TF2 once my item was bigger than heavy...

I exited a quest in Fable II and found that every NPC was frozen in place.

It was pretty neat, but it ruined my save.

The worst kind is when you can't finish a level because something happened to script, something got stuck etc. I don't mind normal bugs cause games are not perfect but those that won't let you finish a game are the worst.
And I hate when achievements don't unlock when they should (Serious Sam 3: BFE or Darksiders, both on Steam).

There was this little gnat flying around my monitor. It was horrible. :s

I hope they paused for you. When I had a bluescreen, these damn kids unpaused and I got an abandoned.

Blue Hell in Grand Theft Auto titles and other various 3D games.

But then, sometimes it is fun to play with that. :P

Skyrim -- The whole thieves guild started attacking me for no reason? And I just deleted all my previous saves. After 100 tries I found out I could lower the difficulty immediately in the options menu. Ran outside and never came back!

Get To Know Jack quest in Borderlands 2. It was literally impossible to complete it.

Chocolate covered grasshoppers x p

The bugs in my doodles ;_;

On my Nokia (symbian) I have a Solitare and Freecell game (both from same dev) that randomly bugs out and I can't move the cards I desire to the location I want. They just don't stick. So yea...this is it.

Skyrim: On my first playthrough, I had to escort some guy (i think he was called esbern) from the ratway, but he wouldn't open the door he was behind and I couldn't open it either. It was a main quest, so I was basically stuck. In the end I had to use the console to finish the quest.

Also in skyrim right now, I can't load any new saves. It just crashes upon entering the loading screen, so I can only load old saves.

The worst bug was for I think half life 1 (or was it blood 2, sorry was long time ago, in 1998 or 99). When you uninstall the game it would delete everything on your partition where the game was installed. They fixed the bug latter, but the dmg was alredy done.

Damn, you are all having pretty bad gamebreaking bugs :O mostly in Skyrim, I had only one major bug there and that was the water not being shown ^^

cockroaches

I can't remember the worst one. The latest one was in Ristar, when I got behind the boss in the ice level and it did that breathing in attack. It ended with Ristar getting dragged into the middle of the screen and spinning endlessly.

Finch's Slaughterhouse in BL2

once i completed a round, all the enemies would be dead, but it wouldn't start the next round

i retried several times, but no :( and since you cant leave of your own accord, i had to either kill myself or force end BL2 just to get out xD

so yeh, not game breaking, but still annoying (and it STILL hasnt been patched)

this is the page for it

In GTA 3, i remember i did like one of the hardest missions in the game, took me like 10 minutes, and i was escaping from the cops in the end, had 4 or 5 stars on me, so i had a crash with my Banshee, the car flipped and i couldn't get out because of some fucking wall or something. WORST, i didn't even same the game in the last 5 or 6 missions.
So, basically i stood there 5 minutes trying to get the hell out of that car, without any success. I ended up going to the menu and loading the last save game.

Another thing that happens a lot: I play a lot of L4D, and i just hate when zombies get stuck in things and you can't bash them. You're there trying to bash them, but they just don't move and keep hitting you. It sucks since i always play on expert and lose 20hp per hit. Also, that happens more when you're in small places, like in vents. It sucks.

I had a lot more experiences with bugs, but can't remember more right now...
If i do, i'll post here.

In Far Cry 3, I start playing for about 1/2 hours and for some reason, it crash.
Then I found that I have to start the game from the beginning cuz I couldn't save during the first long tutorial mission.

Spawned inside of a house on day-z.

Final boss of Dark Sector on PC. I was throwing the final glaive to kill him, then...the game minimized for no apparent reason. I open it back up and I'm dead :/

ARMA: Cold War Assault
Everything was working fine until I completed one particular mission. Now I've lost all progress (it's a loooong game) and can't start the game anymore.

I had a weird bug with Cave Story a while ago. I had just started playing the game and saved my progress to continue playing later. After a couple of days I decided to continue my game, but the save was nowhere to be found. Luckily I hadn't gone very far in the game, so I could easily catch up to where I was in my save. The game had these halloween texture changes during the days I wasn't playing, so I'm suspecting those somehow screwed up my save file. :/

In Dark Souls, if you slide down the ladder from Sunlight Altar to get below the Undead Parish bridge you'll fall into an endless pit of death. Not worst, but you can imagine the rage.
