History YMMV / X

* CanonDiscontinuity: The albums recorded following Billy Zoom's 1985 departure are largely ignored in their live shows nowadays. Exception: "Burning House of Love" from ''Ain't Love Grand.''
* FaceoftheBand: Exene

* UnfortunateImplications: These ''really'' start to crop up if you start to think about who each race represents. Boron are squid, Paranid vultures, Split are warlike humans, Teladi lizards, and Kha'ak are insects/birds. Heck, there's even an unseen, non-space-capable Whale race that's protected by the Boron.

** The Fragmentation Bomb Launcher sounds like a dangerous weapon. It's [[SpaceIsNoisy loud]] and produces a pretty explosion. But it burns weapons energy fast, and unless you manage to hit the target ''before'' it detonates and produces its FlechetteStorm, you're not going to hit anything smaller than a corvette. Its only saving grace is its price tag: as VendorTrash a salvaged or manufactured FBL will net you roughly a quarter of a million credits.

** Almost every unguided missile: they are inaccurate and do very little damage. What's more, they lack actual AreaOfEffect damage thanks to a programmer's oversight (which otherwise could've turn them into niche weapons). The exception is the [[RecursiveAmmo Tornado]], which can be used to rig certain M3 fighters (chiefly the Falcon Hauler and Falcon Sentinel) as bombers for anticapital work.

** Continuing on the low-tier spectrum, the Boron Manta and the Paranid Hermes are two of the slowest TPs in their class (the former being 110 m/s and the latter 105 m/s respectively). Time is everything when doing the Marine/Passenger Transport missions and, even with Jumpdrives installed, these two craft are just not cut out to perform these missions.

* GameBreakingBug: Due to a compatibility issue caused by a 2011 map patch, you ''cannot'' use ''Xtended Terran Conflict'' with the Steam version of ''X3''.

** Profitsss.

** The Mosquito Missile was this in the vanilla version of ''Terran Conflict''. It may be the most commonly used missile thanks to its low requirements to produce it, and it has good speed and slightly above average stats. However, it deals a pathetic 200KJ worth of damage (and in case you're wondering, 1 MJ = 1000KJ), meaning it's virtually useless against anything that isn't a fighter drone. With the release of the Bonus Pack for ''Terran Conflict'', the Mosquito has been somewhat RescuedFromTheScrappyHeap due to it finding itself being useful against enemy missiles (and it will launch against fighter drones automatically), thanks in part of the introduction of the Mosquito Defense Script.

** The Kha'ak may be even worse, simply because ''we know practically '''nothing''' about them''. Throughout the series, we have learned exactly ''nothing'' about them aside from their HiveMind and nividium addiction. All attempts to spy and/or study them have ended in failure and/or disaster. They have made absolutely no attempt to communicate with anyone. (even the Xenon occasionally send messages to the Boron, and #EFFA even tried to negotiate a truth when the Xenon were starting to lose) The Kha'ak are utterly alien, and like the Xenon, their sole desire seems to be to destroy anything that's not them. Only in their case, its heavily implied that they ''eat'' their victims. (Compare to the Xenon, who "merely" just kill you)

** The Concussion Impulse Generator ''sounds'' like it can deal a lot of damage, but in reality, it's merely a scaled up corvette-sized version of the High Energy Plasma Thrower. The difference is that it has a terribly low rate of rate, and its improved range hardly matters when it uses up more energy than the HEPT. [[VendorTrash It's better off sold as a commodity in any space equipment dock]]. However, it is entertaining watching fighter craft being spun wildly out of control by the concussive shots. [[ItAmusedMe Or by using it to push freighters into each other]]. However, it does make a pretty good all-purpose weapon for frigates, which have the reactor strength to power it. That is, unless you're flying a Teladi Shrike or Xenon Q, both whom have terrible generators to recharge their weapons. ''Albion Prelude'' buffed all M6 weapon generators so they are much more practical there.

** The Cyclone Missile is derided by many players for having painfully slow speed (148 m/s, the second slowest in the game after the more powerful Remote Guided Warhead) and mediocre damage for its class (23 MJ) despite being commonly found at its available factories; limiting it to use against slower-moving M3 fighters and requiring multitudes of this munition to dispatch them. Considering that it was developed by the [[MartialPacifist Boron]], it isn't surprising. The only positive thing to say for it is its unique ability to [[RecursiveAmmo split up into smaller warheads]] if it misses its target, but that's it.

Its only saving grace is its price tag: as VendorTrash a salvaged or manufactured FBL will net you roughly a quarter of a million credits.

** The Xenon "LX" heavy fighter. While it isn't as common as the M and is a tad slower, it has turret coverage in both the front and rear arcs that can swat out non-swarm missiles. Meanwhile, it's got the same Pulsed Beam Emitters as any other Xenon craft not an N which makes the [=LX=] dangerous for any non-M7 craft. Players try to [[CherryTapping Cherry Tap]] it in hopes of capturing the fighter for personal use, as it is one of the better M3+ craft around.

** "Reboot" in ''Terran Conflict''. Reboot requires you to capture a Xenon "Q" frigate, which is the single hardest ship in the entire game to capture. It requires ''swarms'' of 5-star marines (which take hours to train, and the only way to increase their "fight" skill is to board ''other'' ships, which can result in causalities). Massive amounts of SaveScumming is required to get the achievement.

** Any ship with a Plasma Burst Generator. They're nigh-impossible to dodge, fire quickly, and burn through shields and hull in seconds (unless you're flying an M7 or higher).

** Pirate and Xenon M5s. They do very little damage, but they come in groups of 3-10, and they'll just swarm around the player ship, slowly plinking it to death. These ships are moving around at ~300m/s, making conventional weapons useless against them, as the scouts are constantly adjusting their flight path. Mass Drivers, Impulse Ray Emitters, Particle Accelerator Cannons, Pulsed Beam Emitters, and Phased Repeater Guns are usually the only weapons that can hit them effectively. The Plasma Burst Generator can work wonders on them, as well; if they get within your weapon's arbitrarily short range.

*** The Cluster straddles between this trope and DemonicSpiders. Basically, it's one M3 combined with several M5s or M4s to swarm all over your ship to make your life difficult. A Plasma Burst Generator or a sufficiently powerful tracking missile can one-shot all the fighters except the M3 when they're about to break off, otherwise you better hone your piloting skills against these.

* WhatDoYouMeanItsNotPolitical: InUniverse, the reason for the games' EnergyEconomy is a piece of Community of Planets legislation called the Energy Accord that bans nuclear reactors aboard space stations, put in place due to government and civilian reaction to a major reactor accident aboard an Argon space station in 2773 AD. Remind anyone of the kerfuffle over Three Mile Island, which stopped essentially all nuclear reactor construction in the United States? (Fukushima hadn't happened yet.)

** However, in a rather extreme case of AllThereInTheManual, the X-encyclopedia details -why- [[spoiler:the Argons struck at all, noting that the Terrans infiltrated the Argon Federation with spy ops to secretly influence the course of the Community of Planets.]]
