Blizzard Tracking 180,000 Bugs in WoW

You'll never guess how many bugs are in Blizzard's MMORPG.
How many bugs does it take to fill an MMORPG? 180,000 of them apparently, or at least that's how many Blizzard is tracking in World of Warcraft. Currently there are 180,000 bugs listed in Blizzard's database, including those that have already been fixed, those that still need addressing, and bugs that Blizzard is currently stomping.
According to Wow.com, the startling revelation came yesterday at the Austin Game Developers Conference, spouting from Executive Vice President Frank Pearce and Production Director J. Allen Brack. Their presentation focused on what takes place behind the scenes of a MMORPG and how everyone gets their job done. The news surprised the conference attendees in respect to the actual number as well as Blizzard's honest admission.
PC games by nature, bring problems to the table due to random consumer hardware configurations, however games such as World of Warcraft and Age of Conan are consistently larger than the average title. Throw in the fact that the server side code remains active twenty-four hours a day, and additional external elements creating havoc in gameplay, developers stay rather busy patching security holes and improving code.
Unfortunately, the company didn't reveal its long list of bugs. Then again, perhaps we're better off not knowing, but to instead just enjoy the virtual world and let the subscription fee take care of the worries.

Hmm... I wonder how many bugs are on Windows and Mac?
There are 12 million bugs in WoW,
its the players.
"Then again, perhaps we're better off not knowing, but to instead just enjoy the virtual world and let the subscription fee take care of the worries."
Because this approach always works. The Dev who wants to delay a year to curb half these bugs finds himself browsing Monster the next morning.
This includes bugs that have already been fixed, that said, that number isn't all that surprising.
You guys really need to tone down your headlines. It should have read "warcraft has had 180k bugs over its lifetime".
Or you could tell us how many they are currently working on. Stating 180k are currently being tracked, when you then admit that they are only tracking a portion of that, but have notes on others they already fixed is silly.
No need for the scary headlines.
They are tracking ALL 180K bugs. They never said they were only tracking a portion of it. They are still tracking the bugs they have fixed. Obviously to make sure they stay that way.
so......180k bugs since the day it released....years ago? What's impressive about that? It's a huge game that's been evolving for years with constant updates to content and gameplay. That's like a news headline reading "Humans have invented millions of things". No shit, we've been around for *%#*ing ages.

180k bugs hmmm I wonder how many must be in gta iv in all versions.

If the story was "WoW has had a lot of bugs," it would be obvious and pointless to anyone with any experience with the game (or any MMO). The fact that an actual hard number was revealed is interesting, just as it would be extremely interesting to get a hard number for how many things the human race has invented, though that would obviously be impossible to track accurately.
If you asked people to guess how many bugs WoW has had, you would get numbers likely ranging from a few hundred (those with no sense of scale) to a few million (those who think a slightly misplaced hair on a wooly mammoth would be tracked as a bug). The scale isn't a revelation, but the hard number is interesting to see.
lol 12 million bugs - 1 cause I finally quit, this time it's for real, i'm not going back!
Wow...
12 million players, and only 180k bug reports?
I must have reported a dozen when I played... if you don't report a bug, how will it ever get fixed? That holds true for any software.
And yet, perhaps surprisingly given its scope, out of the MMOs I've played WoW is the one with the far fewest issues. The one with most being WAR.
That is pretty rediculous of course. I should tell 180k problem reports.
The same bug may appear as 10k problems in different circumstances.
Just that few?

People don't understand programming, do they?
I disagree...there's only 1 bug in the game: its existence.
Given thye size of the project I wouldn't be surprised if there were 180k unique bugs reported before the beta was finished. Consider all the subsystems in the game, the interaction between servers, and possible balance issues. If a skill is over powered it gets a bug. If an icon is wrong it is a bug, if a shadow isn't drawn correctly it might involve a half dozen bugs. Even if individual developers code perfectly you will still have integration and design bugs that appear when you combine their work.
WOW! Call the pest control guys!
LOL!!!! I wonder how they are dealing with Diablo 2... still waiting for that patch and I bet the bugs that have been reported since years ago still won't be addressed. I know D2 is not subscription, and that they are throwing us a bone with a new patch, but still, the bugs have been flagged, documented, even modders have offered advice on how to correct the issue without making large modifications yet still no fix. >_>
someone call an exterminator
If a skill is over powered it gets a bug.
Don't confuse balance issues with bugs. If for example Death Knights are doing more damage than intended, it's not a bug, it's a balance issue. The skills are all working properly, they're just combining to create more output than the developers expected.
Now, if the skill is overpowered because it has a 200% spell damage coefficient, instead of the 80% intended, then it's a bug
Zendax, I understand the distinction. I was thinking more from a what happens internally perspective. In the beta programs I have worked anything that requires investigation or a change is opened as a bug after the initial coding pass (prior to the initial coding pass all data and work units were in a spec).
The problem may be a poor design choice ("Hey it is working exactly as intended/specced, but the customers hate it"), a coding bug, a typo in the help or other problem. Bottom line is that if it wasn't in a bug it couldn't be assigned to a developer, artist or other member of the team to consider. When you follow an internal process like that far simpler products than WoW can 'ship with 100K bugs' in the database. Of course X percent of them will be duplicates, Y percent will be resolved, Z percent will not be reproducible, etc. However it makes for nice headlines if the press gets the number.
One other thing - after the initial coding pass some companies will use a bug to spec a new feature and assign it to a developer. Need to add the kitchen sink into the product? No problem. Open a bug, specify that this is a design change, select the proper category, describe it, write a justification and submit it to the queue for assignment to the proper personnel (who will accept, reject or defer the change).
It isn't a bug in the usual sense. The company is simply using their bug database to track and assign work. From an accounting and business management point of view the reasoning is - why have two processes where most of the steps are shared? Make and document one process for all product changes. Saves money and prevents internal confusion.
Still even over it's lifetime a 180k bugs is really COSTLY. You have to wonder what's the average cost per bug. I mean you have to repro it,track it, fix it?, test it, etc... Even if you pay the QA team third world wages it's going to cost you alot of money at the end of the day. Always better to test more before you release the product...... On the other hand doesn't say how many of those bugs were fixed before being released either.
I think this is a smart move by Blizzard to be open about the bugs in their software. For one, they're sorta promoting themselves by admitting that it's a really huge game so inevitably will have some bugs, unlike some others *cough* apple *cough*. The other reason would be to let their subscribers know that they're actually doing some work with our money. So by openingly discussing some of these issues with us, I think it's a win-win for Blizzard.
No offense to any of you folks, but 180 000 bugs over the span of nearly 5 years and in an MMORPG I think is admirable not a shame.
Imagine this:
Game development is a staged process:
Concept
Design
Coding
Animation
Scripting
Polishing
Revisiting
Rethinking strategies
Rethinking concepts, designs, coding...etc
Realizing changes
Polishing
Bug testing
rinse and repeat
This is a process that takes years before the first version even gets released.
After release the real mass bug filtering will start, as not a single game developer can possibly keep into account ALL of the different user hardware/software combinations.
People always rag on any and all game developers for bugs and flaws without thinking even once about what kind of work goes into the making of a game.
It's very easy to only look from the "me" perspective and think about the problems you encounter and how it all effects you... but the truth of the matter is that you are only one in so many users. For you there are possibly millions of others who have not a problem in the world with the game in question.
Please remember peeps, the world doesn't revolve around us as individuals.
Take it easy folks, and keep your chins up.
Peace,
Mike
They still will not fix the vanish bug for rogues.
I would guess 97% of these bugs never made it into the final product. 180,000 is a good indicator of the size of the project and the effort required to maintain it.

Like any form of media, the truth gets "touched up" to lure in readers. It's just like the Daily Bugle vs Spiderman.
Hardly a surprise that the game contains a shitload of bugs. After all they're changing things on the client side every 2 weeks, and on the server side even more often. The game's changing all the time, and subsequent bugs are unavoidable.
ps. the server side code doesn't stay in use 24/7 - once a week all servers are rebooted, and more often if severe bugs occur.
Well, considering that the bugs aren't always with the game engine themselves, but for each quest, I guess that's OK. A bug can be a simple little thing like a NPC twitching or abnormal behavior when doing a certain quest.
