- Base Breaker: In a rather Base Breaking moment, when it was revealed that the official SP campaign for ARMA 3 would not be finished in time for the scheduled September 12th release and that said release date was immutable, meaning that the game would ship/launch without an official campaign... the announcement that the campaign (or rather, three mini-campaigns) would be delivered as free DLC didn't help at all.
- In Arma 3 DL Cs are a great point of contention among players: in order not to fragment the multiplayer community, Bohemia takes a "freatures free, new content is paid for" approach, making players who own the DLC to have access to content other players in the same server don't have. To ilustrate, the Helicopters DLC introduced game mechanics such as sling loading, advanced flight model (as in ''completely'' realistic), firing from vehicles, and a few more. These are available to ALL players, regardless if they pay for the DLC or not, and they apply to all helicopters, including the non-DLC ones. But the new helicopters added in the DLC, can only be piloted and gunned by players who paid for it, while other players in the server can still ride as passengers, wether they own the DLC or not. Some players think this is fair, others think it is not, others just complain about the existence of DLC at all. And let's leave it at that
- Cult Classic: The first game. And the second game before DayZ.
- "Funny Aneurysm" Moment: The 2014 invasion of Crimea and civil war-like situation in Eastern Ukraine is uncannily similar to the scenario and plot of II; A radical Russian minority with a Communist bent in a post-Soviet Central-Eastern Ruritania bordering on Russia wages war against weak government forces (after the latter declare to distance themselves from their Cold War sphere of influence) and occupy government buildings. Then Russia personally intervenes, marching over the border in a semi-black-op manner. Then the government forces team up with radical nationalist militants. The only part that has yet to happen is a US-European military intervention.
- Game Breaker: Not really present in game mechanics in the traditional way, since it's comittment to realism means that nothing grants an automatical advantage over everything, every weapon and vehicles has its advantages and disadvantages, making the game breaker status more dependent of the situation rather than the weapon or vehicle itself. It is up to the mission designers to make sure that no element becomes all-powerful (I.E: If one team has access to attack helicopters of some kind, the other team should have Anti Air capabilities in some form).
- Homegrown Hero: Arma regularly casts you as an American soldier in NATO intervention and/or peacekeeping operations in fictional countries. Sometimes it's actually closely based on Real Life (like in II's Yugoslavia-esque Chernarus and Afghanistan-esque Takistan) and thus downplayed, but other times (as with Sahrani in I or Altis and Stratis in III) not so much. The creators themselves are Czech (and have once even made a Czech faction in-game), but the intended target market audience was obvious.
- Just Here for Godzilla: When the Day-Z mod came out, ARMA II sales spiked — even amongst people who admitted that they were NOT at all interested in the base game.
- Narm: Like OFP, the Mad Libs Dialogue. Also any time Kozlowski (not the same one from OFP) opens his mouth. Also again, Armstrong tends to indulge in Dull Surprise.
Kozlowski: (in a slightly high-pitched voice) Oh, fuck, those murderous pigs!
Armstrong: (badly wounded) Need! HELP!
- Memetic Mutation: When the third planned livestream (pre-Gamescom 2013) was cancelled due to bandwidth problems in favor of recording the video offline and then uploading that, thereby implicitly cancelling live Q&A, participants in their Twitch chat started mocking the official explanation of weather impeding BI's Internet connection with increasingly more ludicrous versions:
One example livestream chat room participant: Due to the Takistani militia bombing the net cables, the video is being recorded offline and will be uploaded in aprox. 2 hours - Check the BI social media channels for updates"
- Scrappy Mechanic: The anti-lag features in ARMA III are notoriously infamous for being too strict, even in situations when the players' internet connection starts to fluctuate for outside causes: You must have always a ping connection below 300 if you want to play the game online or keep playing the game on any moment. If your connection goes above 300 for a few seconds, you can forget about playing the game at all.
- The new scope sway, weapon resting and fatigue system added in a few updates has been mostly disliked by less realism fixated players. Weapon resting and bipods in particular were requested for a long time but most people now regret the addition, mostly because they worked as intended. To elaborate: while scope sway always existed, it was fairly reasonable and manageable, but with the adittion of weapon resting (a passive stability bonus when a weapon is touching a surface such as a window frame), scope sway and recoil was notoriously increased in order to make the resting an actual advantage. Meaning shooting with a scope while standing with long range scopes and higher caliber is practically useless. Bipods and deployment were another addittion long expected but bipods restric heavily the angle you can aim and it deploys parallel to the ground. In other words, going prone on a hill and using the bipod will make you aim downhill. This makes the act of sniping (a major attractive of the game) even harder than it was before, since the hiding place you choose is much more influent in your aiming.
- In a similar way related with the above point, the game is notoriously unbalanced for players with low-spec PCs against players with high-spec PCs. A player with a very powerful rig being able to render the game at 60 fps will always be in a technical advantage against any player with a weak PC that could only render the game at 30 fps or less, since at the moment the player with the less powerful PC could be able to draw any weapon, the player with a more powerful and expensive rig already killed the player with a crappy PC and the other player are unable to do anything else afterwards forcing those kind of players to use other indirect methods to do combat, like using tanks, anti-air artillery, etc. While other FPSs have methods or systems to avoid this, on the other hand this is enforced in the game in a attempt to keep a seemless gameflow during all moments of online play.
- They Changed It, Now It Sucks: The Bohemia Interactive boards flew into a nerd rage when it was found out that ARMA III's single-player campaign was a sandbox game set in 2035 with a "future warfare" aesthetic, crying and sobbing about how it was going to be more unrealistic — when much of the hardware displayed was already in military use in real life.
- Most of the changes made to gameplay are met with derision until player get used to them, the stamina system, weapons resting and deployment, advanced flight model, etc. All were met with Ruined Forever!!!! cries but they all died down eventually.
- It got worse when the official marketing buzz in 2012, particularly at the E3 2012 showcases, focused wanting to make ARMA III accessible and "streamlined" (complete with the creative director joking "let's not be afraid of that word") and in particular to make infantry more fluid. When assault rifle recoil during the infantry showcase appeared to be lighter than in any previous ARMA game — and when previewers noted that the gunplay felt more like a conventional first-person shooter — outraged complaints flew of BI making the gunplay too "COD like"... and this was all before the announcement that Arma 3 was going Steamworks and thus would require a Steam account and the Steam client to play.
- To say nothing of all the complaints about the gameplay, ''especially' once a gameplay balance designer was hired, and after a dev said that an unrealistically slow rate of fire for an anti-material rifle (its real-life counterpart is semiautomatic) was working as intended for balance reasons... then at E3, the revelation that the Take On: Helicopters flight model would not be implemented by release, nor were requested-for-years features such as weapon resting (despite being acknowledged) and some systems such as the medical system simplified, with the acrimony on the devs' forums growing...
- Uncanny Valley: See The Stoic. The way the in-game voices issue commands can also approach this, as each word the characters speak is used from pre-recorded fragments to form the commands, which thanks to the sometimes shoddy voice work can sound very different in tone and inflection between words. This leads to a very stilted, unnatural stop-start-stop speech pattern that can be both unnerving and unintentionally hysterical.
