* AwesomeMusic: Pretty much '''the entire point''' of ''Horizon'', other than the cars. The game has 3 music stations: "Horizon Bass Arena", which plays electro, house, techno, trance and dubstep; "Horizon Pulse", which plays pop and indie music; and "Horizon Rocks", which plays rock and metal. Each station has its awesome tunes: "Bass Arena" has Music/{{Skrillex}}'s remixes of "Cinema" by Benny Benassi and "Levels" by Avicii, "Illmerica" by Wolfgang Gartner, "Lick The Rainbow" by Mord Fustang, "The Power" by DJ Fresh and Dizzee Rascal, "Everyday (Netsky Remix)" by Rusko, "Blue Monday" by NewOrder and (best of the best) "Me And You" by Music/{{Nero}}; "Pulse" has "Awake" by Electric Guest, "1901" by Phoenix, "Over and Over" by Hot Chip and, best song of Pulse, "Something Good Can Work (The Twelves Remix)" by Music/TwoDoorCinemaClub; "Rocks" has "Lonely Boy" by The Black Keys, "Give It Up" by Music/LCDSoundsystem and two songs by Music/{{Lostprophets}}: "Bring 'Em Down" and "We Bring An Arsenal".
** What's more, Turn 10 and Playground Games even nailed it on the trailers, with songs by artists such as Zeds Dead, The Anomalies and Netsky. For this last artist, the songs that appear are: "We Can Only Live Today (Puppy)" and "Come Alive". This last song, for your information, is downright FITTING for the entire Forza series.
** Hell, pretty much almost all of Horizon Bass Arena and of Horizon Pulse and more than half of Horizon Rocks. Conclusion: Playground Games and Turn 10 really nailed the soundtrack section in Horizon. And if you want to know the whole OST, go [[http://vgost.wikia.com/wiki/Forza_Horizon here]] and get blown away by awesomeness.
*** The soundtrack was all mixed and chosen by BBC Radio One DJ Rob Da Bank. If you want to thank the guy who mixed the game's OST, now you know him.
** ''Forza 3'' has "Trash" by The Whip, "Showdown" by Music/{{Pendulum}} and "Lost Weekend" by The Qemists featuring the one and only MikePatton. And probably the best of the lot, "Tick Tick Boom" by Music/TheHives (cue YEAH! x3).
*** Oh, and please not forget "Suburban Knights" by Hard-Fi.
** ''Forza 2'' has "Spitfire" by TheProdigy, "Put Your Hands Up" by Benny Benassi, "Insomnia" by Faithless, "Body Language" by Booka Shade, "Cobrastyle" by Teddybears, "Gone Daddy Gone" by Gnarls Barkley, "Daft Punk Is Playing At My House" by LCDSoundsystem, "Positive Tension" by BlocParty, and not one, but '''TWO''' songs by Music/{{Goldfrapp}}.
*** Hell, even the trailer song, "Rock Star (Jason Nevins Remix)" by N.E.R.D., is awesome.
** ''Forza 4'' has a soundtrack heaven for Hospital Records and Marine Parade fans. With artists signed to Hospital such as Camo & Krooked, Danny Byrd, Netsky and Nu:Tone, and Marine Parade artists such as Evil Nine and Alex Metric, you know where this is going. And just listen to the game's theme song, [[http://www.youtube.com/watch?v=lRb5Cgy86YM "It Starts"]] by Alex Metric. '''WHOA.'''
*** Other pieces from ''4'' to mention are the three songs by The Qemists from their album "Spirit in the System". The songs are: "Take it Back" (with the special appearance of EnterShikari), "Dirty Words" with Matt Rose and Bruno Balanta, and "Your Revolution" featuring Matt Rose.
*** Not even the launch trailer is safe from this. "[[Music/KanyeWest I'm livin' in the 21st century, doin' something mean to it. Doin' better than everybody you ever seen do it.]] [[Music/MyBeautifulDarkTwistedFantasy Screams from the haters, got a nice ring to it. I guess every superhero need his theme music.]]"
** According to Dan Greenawalt, ''Forza 5'' won't feature a licensed soundtrack. Instead, it will feature an operatic, epic movie-like soundtrack which adapts itself to every situation. '''It is glorious.'''
* BreatherLevel: Bowling and Car Passing events in ''Forza 4''.
** The 1000 Club in ''Horizon'', a free DLC that gives you two cars (an old Ford pickup and a 90s RUF) and over 1000 minigame-style challenges across every car in the game, some of which are simply to perform basic skills or destroy stuff on the side of the road!
* BrokenBase: ''Horizon'' caused this, splitting the fanbase into two: a part supporting the spin-off and liking the open-world mechanic, the other attacking the game [[HateDumb because it's not the]] ''[[HateDumb Forza]]'' [[HateDumb they have been used to.]]
** Also, ''Forza 5'' having less cars and tracks than ''4''. One side thinks that it had to be done because of ExecutiveMeddling, others mourn the absence of long-time-loved circuits such as [[MarathonLevel Camino Viejo]], [[SceneryPorn Sedona]] and [[ThatOneLevel Fujimi Kaido.]]
* ComplacentGamingSyndrome: ''Forza 3'' often had multiplayer games composed ''entirely'' of Audi A5s and A4s. Other "Leaderboard" cars (cars that have the top times for each track) dominated the multiplayer, but none quite as hard as the Audis. Thankfully, the behavior has died down quite a lot in ''Forza 4'', as there are only a few game-breakingly good cars (and players usually get votekicked out of the lobby once they pull out the car).
* ContestedSequel: ''Forza 5'', believe it or not. Despite being just as critically acclaimed as the other games in the series (and that means ''acclaimed like there's no tomorrow''), it met mixed reception from the fanbase.
* FanDumb: ''Forza'''s Facebook page is littered with people complaining that the cars being added in DLC packs have no place in a racing game; these are usually the same people who want a Chevy Cavalier or a 90's Toyota Corolla simply because they own one in real life.
** Another frequent complaint is that they never add new tracks. This was because said "fans" never bought the two track packs for ''Forza 3''.
* FandomRivalry: With ''VideoGame/GranTurismo'', obviously.
** In 2012, between the fans of ''VideoGame/NeedForSpeed: Most Wanted'' 2012 and of ''Forza Horizon''. These two games are completely different, but they have exited around the same time (during Halloween and All Saints Day), share a lot of the same cars (even in later DLC for both games), are open world racers[[labelnote:*]]Both games' locations (''Most Wanted''[='=]s Fairhaven and ''Horizon''[='=]s rendition of Colorado) are [[SceneryPorn gorgeous]], by the way.[[/labelnote]] and, the straw that broke the camel's back, they both have a song in common: [[CrowningMusicOfAwesome "The Power" by DJ Fresh and Dizzee Rascal.]]
* FridgeLogic: In ''Horizon'' there are non-street legal cars such as the Ferrari [=599XX=] and the Maserati [=MC12=] Versione Corse. In real life, you could be arrested for driving these cars on open roads, but not in ''Horizon''.
** The fact there is no police presence is even more questionable: the radio [=DJs=] allude to street racers being picked up by the cops, yet nothing like that is ever seen.
** Cars don't have license plates in ''Horizon'' either. WordOfGod says that as the car manufacturers are supplying the cars to the Horizon Festival (which is true, as radio chatter confirms this), this means the player is effectively buying them for pure competition/race use, meaning they're not meant to be on the road and thus, don't need plates. Still odd though: then why you're perfectly able to drive through the open roads?
* GameBreaker:
** The Honda CRX in the first game falls into this due to improperly set drag values.
** In a sense, modification, as in ''Forza 3'' and previous games, the AI never has upgraded cars.
** Things can get deliciously broken when you take a car that ''technically'' qualifies for a given race but which no human judge would allow entry. An example, the French Elite Invitational in ''Forza 3''. Usually this is the stomping ground of Peugeot and Renault hatchbacks, but things get interesting if you're bastard enough to bring a Bugatti, or even more, a Peugeot 908 LM!
*** Even better, at driver level 20 the game gives you a Veyron for free.
** Due to how ''Forza 3'' calculates a car's Performance Index (in other words, how "fast" a car is going around a track), All-wheel-drive drivetrains cause your performance index to actually go ''down'', since it adds about a hundred pounds to the car. However, this allows players to then install huge engines, or cut weight from the rest of the car. What effectively happens is online play gets dominated by AWD Audi A5s, Dodge Vipers with AWD drivetrains, and AWD Volkswagens
*** As of ''Forza 4'', these problems have been fixed; AI can be allowed to upgrade their cars, events now have an upper PI limit, and AWD cars/conversions have more PI rather than less.
*** However, upgraded muscle cars are tremendously fast for their class. As a result, a few muscle cars have been banned from setting leaderboard times while the problem is addressed.
** In ''Forza 4'', Rivals mode is ''very'' easily abused. By continually going only a fraction faster than your previous effort you will collect many more bounties than if you set your fastest time straight away.
** In ''Forza 4'', preforming rear-wheel-drive swaps on cars (like making a Honda Civic, normally FWD, into a RWD Car) causes a ''massive'' performance index number drop in cars without any real drop in performance - allowing you to slap on weight removals, turbochargers, and bigger tires without much of a PI increase from the stock car.
** ''Horizon'' gives us the Pagani Zonda R. Fast, nimble, [[CoolCar and even gorgeous.]]
*** Tch. Meet the [[http://en.wikipedia.org/wiki/Lamborghini_Sesto_Elemento Lamborghini Sesto Elemento!]]
*** Another example of GameBreaker in ''Horizon'', other than the Pagani and the Lamborghini, is street races. They can net you at the very least the same amount of money if you place first in the final few Festival races (the ones where's also [[FinalBoss Darius Flynt]]), and from that point on, the last few of the street races give you 50-60 thousand credits. And it only gets better if you (ab)use the HardModePerks.
** ''Forza 5'' gives the Lotus [=E21=] FormulaOne car. [[InfinityPlusOneSword At first it was the most expensive car in the game, and for good reason]]: 1) it's quick and astoundingly fast; 2) it starts very quickly off the line even without driving aids; 3) its handling is wonderfully touchy, you can pretty much handle many corners throughout the game almost flat-out. Even better, it is now available as a gift from Turn 10 after the economy update. Yes, this car is pretty much a huge load of badass-ness.
* GoodBadBugs: Certain clever maneuvers in ''2'' might allow you to earn obscene amounts of cash. As a consequence, the inflation levels in the Auction House are ''astounding''.
* HeartwarmingMoments: [[http://www.youtube.com/watch?v=PvimE0aNFOg This commercial,]] from the ''VideoGame/DeadIsland''-grade sad piano, to the man's attempt for automotive thrills till he's stopped by police, and the icing, an oddly thoughtful narration by [[Series/TopGear Jeremy Clarkson.]]
* [[SuspiciouslySimilarSong The Junkie XL Version]]: A lot of the songs in the first game were done this way. The songs are all remixed versions of actual rock and metal songs of TheSeventies, such as "La Grange" by Music/ZZTop.
* MemeticBadass: M. Rossi in ''2'' and ''3'', though "Memetic Bastard" might be a better way to put it. Who knew an otherwise imperceptible character could be such a universally-reviled JerkAss?
** Apparently, according to Dan Greenawalt (The Creative Director of Turn 10), M. Rossi even scared the developers.
-->'''Dan Greenawalt''': One driver, M. Rossi (no relation to the great V. Rossi) is one of our fastest and most aggressive drivers. Late in development, he started learning things that we hadn't taught him. He started check braking (A very advanced racing technique, also sorta dirty). Anyway, this was a bit of a scary moment. He was learning faster than we were teaching.
* TearJerker: The [[http://www.youtube.com/watch?v=_4q2KjWG-9Q&feature=channel_video_title Endangered Species]] trailer.
* ThatOneLevel:
** Silverstone. It seems to be the [[CreatorsPet dev's pet level]], because it comes up ''constantly'' in the single player events. One of the most boring tracks to look at, boring to drive on, and it's ''full'' of 90 degree corners, making it an absolute nightmare to drive on online.
** ''Forza 4'' has two Track Day events that earn the scorn of most players, thanks to the [[SarcasmMode excellently driven]] AI cars:
*** The Fujimi Kaido event puts you on the arguably the trickiest circuit in the game in an A-class car making your way round superminis and city cars. The combination of steep narrow roads and sharp, blind turns only make the AI even slower [[ArtificialStupidity than usual]], and if they swerve across the road there is no space for you to avoid them. And on the one stretch of relatively straight road, an AI car has usually '''come to a complete halt'''.
*** The Nurburgring event isn't much better. You are in an S-class supercar on the "Green Hell" passing small hatchbacks and a couple of [=SUVs=]. The width of the [=SUVs=] means they will back up many cars behind them that cannot get past. And yes, they are by far the slowest traffic cars on the circuit.
** New York City in ''Forza 2'' and ''Forza 3''. It's basically 2 straightaways on Time Square, three 90 degree turns, and a roundabound, making it tiring to race on. It's even worse in 3's "New Circuit" version, which adds a chicane on each straightaway - the chicanes will take out ''at least'' one person per lap, the chicanes are so narrow that if one car wrecks, ''all'' the cars wreck. And finally, the chicanes are placed at the perfect distance to make passing almost impossible unless your car is far, ''far'' faster than the person you're passing.
* TierInducedScrappy: ''3'' has lots of the High Tier varients of this trope in the "Leaderboard cars", so called because [[GameBreaker they always get the best times on the leaderboards]]. Some examples include the Dodge Viper and most things made by Audi (but especially the [=A5=])
** ''4'' has its fair share (see GameBreaker above).
* TheScrappy: M. Rossi in ''3'' and ''4'', and Hailey Harper in ''Horizon''.
** Hailey Harper has [[CrowningMusicOfAwesome "Bring 'Em Down"]] as her theme song and [[EvilIsSexy she's hot.]] So you might be asking, why is she TheScrappy? Because she will not hesitate [[JerkAss trash-talking you like there's no tomorrow.]]
* UncannyValley: Whilst it's nowhere near as bad as some other racing games, a few of the car models (which have been re-used since the first ''Forza'', mind) do look a bit inaccurate compared to the real car and indeed other cars in the game. A good example is the 90's Acura NSX; the front end is out of proportion, and the back end is far too angular.
