* [[BannedInChina Banned in Germany]]: Whilst the first two games aren't exactly banned, Microsoft never submitted them to the USK since they wouldn't get the 16+ rating they were aiming for. Finally averted with ''Gears of War 3''.
* BTeamSequel: ''Gears of War: Judgment'' is the first title developed by People Can Fly rather than Epic.
* CrossdressingVoices: The Berserkers are actually voiced by Creator/DeeBradleyBaker.
* ExecutiveMeddling: Microsoft pushing the release date of ''Gears of War 3'' back five whole months from April 2011 to September 2011. It is arguably a positive example of meddling, members of Epic Games have said the delayed release gave them more time to refine the game, they would not have done a multiplayer beta if this had been released as scheduled and that helped polish everything to a spit shine.
* GameEngine: This is the first ''Unreal Engine 3'' game to be released, oddly enough NOT being an ''VideoGame/{{Unreal}}'' title or a PC game (initially) like the debut games for earlier engine versions. Early ''Unreal Engine 3'' tech demos from 2004 even used ''Gears Of War'' assets rather than ''VideoGame/{{Unreal}}'' ones. ''Gears of War'' was made largely as a demo for the engine, with each succeeding game further enhancing it's capabilities. It's worked well, as several very popular games have been made with the engine.
* IKnewIt: [[spoiler:Before ''Gears of War'' 4 was released, many fans jokingly speculated that Baird was the one who created the [=DeeBees=] that the reformed COG uses since they shared the same initials as him. The campaign proved the fans right by revealing that over the 25 year TimeSkip, Baird became a FamedInStory world-renowned industrialist who, being the resident GadgeteerGenius of the COG, is indeed the creator of the [=DeeBees=].]]
* TheOtherDarrin: Jace goes from having an Australian-sounding voice in his cameo in ''Gears of War 2'' to being played by Michael B. Jordan in ''Gears of War 3''.
* TheOtherMarty: As shown in this [[http://www.crunchyroll.com/anime-feature/2015/02/02-1/feature-interview-with-voice-actor-christopher-sabat interview]], Creator/ChristopherSabat recorded lines for Marcus Fenix in ''VideoGame/GearsOfWar2'' during the [[https://en.wikipedia.org/wiki/2007%E2%80%9308_Writers_Guild_of_America_strike 200708 Writers Guild of America strike]] that affected the LA {{unions|in Hollywood}} (thus having the game be moved over to Texas for voice recording due to its non-union environment, effectively bypassing the union-related issues) [[note]]As he's a Texas-based actor[[/note]] until the game was moved back to LA to be recorded once the strike ended.
* WhatCouldHaveBeen: The series staple, the Lancer/Chainsaw Bayonet, was on the edge of whether it was going to be actually included in the game. It wasn't until they devised the design of it being integrated into the grip that they devised a semi-plausible chainsaw mounted assault rifle. Somewhere, a group of StopHavingFunGuys who want everyone to only use the Gnasher are cursing their rotten luck.
** Baird and Cole's roles were originally reversed, with Baird being the one who was a former sports star.
** Epic Games had originally planned to allow players to choose the gender of Dom, potentially making him into the female Dominique, but the idea was scrapped, as having two genders for Dom would've drastically increased the length of the script and limited the budget, so female characters wouldn't become playable until ''Gears of War'' 3.
** The RousingSpeech given in the beginning of ''Gears of War'' 2 was originally supposed to be narrated by Hoffman, but he lost out when the developers created Prescott, as they felt the speech was better suited for him instead.
** Originally, Hoffman was supposed to die in ''Gears of War'' 3. He was supposed to come with Delta to acquire the submarine instead of Dizzy and would've died protecting it while it sailed off to Azura. However, Karen Traviss considered Hoffman one of the few people in the universe who had a historical perspective on the series (he could talk about the world before the war) and didn't want to lose him as a narrative vehicle for the books.
** When playing through Beast Mode in Gears of War 3, one will notice that there are 5 empty spaces in the Locust selection interface. Indeed, there were originally 20 playable creatures to choose from in the mode. Early beta footage showed that the Grenadier Elite was playable; most likely cut for playing identically to the Savage Grenadier, so it was unnecessary to include both grenadiers. The footage also showed that Grinders were originally playable as well; most likely cut for being too easy to sit in the back of the maps and pick off humans from a distance since Beast encourages players to get close to the action. Also, Grinders don't possess melee attacks, so they would have no reliable way to kill Hero units and Onyx Guards. In addition, Reavers were also playable as well. They were stated to have been cut due to the developers having issues with them fitting on the smaller and indoor maps like Checkout and Rustlung. However, since Reavers are very large, it was also probably overpowered since you could potentially just launch rockets over the scenery to get easy kills while bypassing the fortifications. Another minor one, but the Armored Kantus was also shown DualWielding Boltok pistols in beta footage, but was changed to dual Gorgons. Sadly, it is unknown what the other 2 cut creatures were.
** Players hacking into an FPS made by Creators/EpicGames Shanghai, ''Passion Leading Army'', discovered [[http://tieba.baidu.com/p/1940077425?pid=25550992197&cid=0#25550992197 scripts]] of ''GOW2'' that indicated the developement had already went into advanced stages.
