* DevelopmentHell: You can [[http://www.ign.com/wikis/diablo-3/Development_Hell visit it]]. Seriously though, it was in development for 11 years, including multiple reboots and the closing of Blizzard North in 2005.
* DuelingGames:
** With ''VideoGame/{{Torchlight}} II'', released later the same year and created by many of the folks behind ''VideoGame/DiabloII''. They're both great games, but they're [[DamnYouMuscleMemory just similar enough, yet just different enough]] that it's tough to enjoy both.
** With ''VideoGame/MarvelHeroes'', which has been described as "Diablo with superheroes" and even has the team behind the first 2 Diablo games working on it. The MH team enjoys taking lighthearted jabs at Diablo 3 in some updates and notes.
** With ''VideoGame/PathOfExile'', released about six months later as an open beta. Catering to the fans who loved the more grim and mature style and in-depth player control of ''VideoGame/DiabloII'', it's a free-to-play always-online game with a heavy focus on character, item and skill customization, taking notes from ''VideoGame/FinalFantasyVII'' and ''VideoGame/FinalFantasyX'' and sporting a trading system that uses crafting items as currency.
* FanNickname: [[spoiler:Leablo]]: [[spoiler:The Diablo-possessed Leah at the start of Act IV]].
* FlipFlopOfGod: Is the male Barbarian the same one from ''VideoGame/DiabloII'' or not? Some Blizzard employees say yes, others say no. As of the official release, it was finally decided he isn't.

* InternetBacklash: As of August 2013, ''Diablo III'' holds a 3.8 from Metacritic users (including over 1000 negative reviews) for the massive lag spikes for being forced to play online at all times, reduced content (like PvP) that were in the prequel and Error 37 (inability to connect to the game).
* ScheduleSlip: All {{Creator/Blizzard|Entertainment}} products have a release time of "Soon" ([[TradeSnark TM]]). This game began development in 2001 shortly after the release of the ''Diablo II'' expansion pack. It would be ''eleven years'' before it would finally release. It wasn't officially announced until 2008, and then didn't hit beta until 2011, before finally releasing in 2012.
* SequelGap: ''Diablo II'' (2000) and ''Diablo III'' (2012) -- 12 years.
* TrollingCreator: Creator/{{Blizzard}} had to put up with constant complaints about how "cartoony" and "colorful" ''Diablo III'' is compared to its predecessors. As a pisstake to that section of the fanbase, they put [[http://www.youtube.com/watch?v=JeQzJC-vS40 this level]] into the game.
** As part of the 2009 April Fools' reveal of the "archivist" class (a librarian), Blizzard released a mockup of the radial dialogue tree players could use to navigate conversations. Among the cantankerous things the archivist could say was "In my day, there were no colors."
** These ''are'' the people who date their releases and patches as either "Soon" "Very Soon" or "Soonish", all of which they define as any time between now and ''the end of time'' with Very soon being most likely to be closer to now and Soonish to be closer to said end of time.
* UrbanLegendOfZelda: The official site, specifically, the home page, has its own chat gem. After a massive thread on the Battle.net forums discussing whether clicking the gem a certain number of times would unlock the playable version of the gameplay demo seen when the game was released (started by a forum troll and helped by various random people confirming it), the matter was laid to rest when someone looked in the source code of the site, decompiled the flash that operated the chat gem, and determined that its only purpose was to change colors, changing the gem from "on" to "off".
* WhatCouldHaveBeen:
** The Male Barbarian was supposed to be the same guy from 2, but this [[http://forums.battle.net/thread.html?topicId=27508584306&postId=275061593826&sid=3000#0 idea was scrapped]] by Blizzard, possibly because if it was the same guy he'd be 30 years older, and they would have to explain why the game doesn't start him out at level 40+ and fully decked out with high level magical gear.
** A number of features that were mentioned in demo videos never materialized in the game, such as obstacles that required certain class abilities to navigate, in-game cinematics, additional NPC allies, as well as entire dungeons.
* WhyFandomCantHaveNiceThings: Lots of small bonuses, which in normal gameplay only give a small reward (such as extra experience) for free, have been nerfed or outright removed by Blizzard after a few people found a method to exploit it. That method usually consists of endlessly creating and leaving games to repeat the same thing over and over instead of, you know, actually ''playing the game'', but Blizzard's answer usually affects as well the SilentMajority of normal players, who didn't even know about the exploit but lose the small bonus anyway. An infamous example happened right after the start of the first season, where some people reached level 70 in ''less than 2 hours'' by repeating a few bounties that involved killing-free events in Torment 6 (and rushing through monster-plagued levels to complete them), much to the frustration of players who were hoping for a fair competition. Blizzard's answer was to disable those bounties, both in seasons and out of seasons.
