[-[[caption-width-right:330:Saving the universe from [[EldritchAbomination Dark Force]] since 1987!]]-]

{{Sega}}'s answer to the RPG craze of the late 1980's, the ''Phantasy Star'' series was a classic contemporary to DragonQuest and ''Franchise/FinalFantasy''. Having been in the hands of several of Sega's development studios (in chronological order: Sega [=RD4=], Sega [=AM7=] (Overworks/Sega Wow), and Sega [=AM8=] (Sonic Team)), the franchise has taken several different forms since its inception.

The original tetralogy of turn-based role playing games is primarily set in the Algol solar system, focusing on the planets Palma, Motavia, and Dezoris. Across thousands of years, various heroes rise to combat those who would threaten their home worlds, particularly the evil entity known as Dark Force.

Three {{Gaiden Game}}s, mostly focused on ''Phantasy Star II'', were released as well.''Phantasy Star II Text Adventures'' and ''Phantasy Star Adventure'', a duo of text based {{Adventure Game}}s, explored the past of the PSII cast and told an unrelated story set in the same era of the Algol system's history, respectively. ''Phantasy Star Gaiden,'' an {{Eastern RPG}} for the GameGear, took place roughly halfway between I and II in the Copto star system, a sector of space colonized by the Alogols. The protagonists are two colonists, Alec and Mina--the latter being a descendant of I's heroine, Alis Landale. [[NoExportForYou None of these games were released outside of Japan.]]

A number of times, the games of the tetralogy have been ported to newer consoles. At one point, there was even a [[TheRemake Remake]] of the first two games in the tetralogy--''Phantasy Star Generation 1'' and ''Generation 2''--for the [[PlaystationTwo Playstation 2]]. On top of a more fleshed out story (''far'' more in ''Generation 1's'' case) and updated graphics, there were a few additional quests and tweaks made to the remakes. [[NoExportForYou Of course, nobody outside Japan got to see these either]]. A similar remake of ''4'' was planned and a US release bundling the 3 was announced, but the remake of 4 disappeared and the US release along with it.

Sega's continued to make games in the ''Phantasy Star'' series, but they've largely taken place in entirely new settings with only tenuous connections to the Algol System ... well, apart from the fact that Dark Force just can't seem to leave the universe alone. For more information on the sub-series that came after the tetralogy, see ''VideoGame/PhantasyStarOnline'', ''PhantasyStarUniverse'', and ''VideoGame/PhantasyStarZero''.

As of 3rd of May of 2012, the original versions of Phantasy Star 2, 3 and 4 for Sega Genesis can be purchased and played on PC via {{Steam}}.

'''Please add any examples relating to the blue-linked sub-series to their dedicated pages.'''
!!The series provides examples of:
* ActionGirl: From Alis in the first game, to Nei, Rika, and Alys in the sequels.
* [[EarthIsTheCenterOfTheUniverse Algol Is The Center Of The Universe]]: Thoroughly [[JustifiedTrope justified]] in ''PSIV'', as it's revealed that [[spoiler: the entire star system and all that live in it were originally created by the Great Light to imprison the Profound Darkness]].
* ALongTimeAgoInAGalaxyFarFarAway: Inverted. Though the tetralogy's set primarily in the Algol star system, seemingly in it's own universe, Algol is actually a [[http://www.phantasy-star.net/art/algol2.jpg real-life star system]], its name is Arabic for "demon star." [[MeaningfulName Now, think back to the plot in]] IV ...
** Additionally although obliquely hinted at in I, it's confirmed in II that [[spoiler:Earth does exist]] within a far future context, as it's race tries to conquer Algol to colonize it for resources and living space.
* AnyoneCanDie: This series is not even slightly shy about killing off its main characters. ''PSIV'''s WhamEpisode had [[spoiler: Alys dying from the effects of the Black Wave.]] ''PSIII'' never killed anyone in the active party, but was absolutely murderous to the heroes of the first and second generations. And [[KillEmAll then there was]] ''PSII''.
* ArtEvolution: ''PSII'', the {{Gaiden Game}}s, and ''PSIV'' opted for a cell-drawn art style for {{cutscene}}s that was evocative of [[TheEighties late Eighties]] and [[TheNineties early Nineties]] anime. ''PSI'' and ''PSIII'' have a different (but still {{Animesque}}) style. ''Generation 1'' and ''2'' sport their own cel-shaded style as well, distinct from the original ''PSII'' and ''PSIV''.
* ArtificialHuman: The Numans: Neifirst, Nei, Rika.
** The android/cyborgs of III and IV probably count as well. And then there's [[spoiler: Seth]] in IV.
* AwesomeMcCoolname: The Japanese versions have some ''seriously'' WTH-worthy choices for character names. For just a small sampling throughout the series: Rolf was "Eusis", Rhys was "Kein Sa Riik", Crys was "'''Noin'''", and Kyra was "Shess".
* CantDropTheHero: Rolf. ''I'' and ''III'' don't have enough characters per party to use this trope, while ''IV'' selects your party for you up until the end, and then, you only get to choose one OptionalPartyMember to take along with the four required ones.
* CharacterNameLimits: Four letters max.
* ClarkesThirdLaw: Throughout the series, the explanations for the games' equivalent of magic, "Techniques", has differed. For instance, the manual for ''PhantasyStarII'' describes the fire Technique "Foi" as compressing oxygen into a small space until the molecules ignite and create a fireball, suggesting they are technological or psychic in nature. Meanwhile, ''VideoGame/PhantasyStarUniverse'' describes [[SpellMyNameWithAnS TECHNICs]] and their melee equivalent, Photon Arts, as computer programs uploaded to weapons on discs.
* CompilationRerelease: No shortage of these. The SegaSaturn and PlayStation2 both offered collections which combined all four original games into one package; the GameBoyAdvance offered one which combined the first three.
* ConLang / SpellLevels: Techniques from ''PSII'' onwards. The base spells (such as "Foie" or "Resta") are augmented with prefixes, with "Gi" and "Na" strengthening them and "Sa" making them target multiple subjects. This is much less obvious in the English translations with their five-letter limit.
* CutAndPasteTranslation: In this case, overlaps with PragmaticAdaptation and {{Macekre}}. Due to differences in language, a name in Japanese that easily fit in a short space ''can't'' when translated to a Western alphabet... and due to the hardware limitations of the era, simply making more room for "proper" English wasn't in the cards. As a result, localization teams often had to make new names for characters and items, but they often ''went out of their way'' to change the names into something entirely different--even for names that didn't ''need'' to be changed. They weren't consistent about the replacement names used, either.
** And then there's the mistranslation of Dark Force into "Dark Falz"... Which ended up becoming the canonical name for the godlike cosmic horror that would debut in ''Online'' and have final boss roles in multiple games after that. Whether the name was the ''result'' of the mistranslation or just a coincidence is unknown, though it's still amusing in hindsight.
* CuteMonsterGirl: Nei and Rika, Numans in general.
* DarkerAndEdgier: Compared to many [[EasternRPG JRPGs]] of the period, the series was far darker and far less willing to [[PlayerPunch pull its punches]]. The first game ''started out'' with the heroine's brother being casually murdered by government agents, and the second through the fourth established that not only [[AnyoneCanDie can anyone die]], but that important characters ''will'' die and that your actions and failures ''will'' have consequences even if you succeed.
* DeadCharacterWalking: Can be done in the second ''PhantasyStar'' game. First, kill off everyone except [[SpoonyBard Shir]], then enter a shop repeatedly until she steals something and leaves the party. You'll now be able to walk around with an all dead party, though the second you get into an encounter, you'll die immediately.
* DevilInDisguise: In ''PhantasyStar 4'', you are accompanied for the span of one dungeon by an adventurer named Seth. While his name doesn't really say anything of what he really is, using the Talk command from the menu gives subtle hints, and his abilities (most, if not all of which were used in previous fights by [[spoiler: Dark Force]]) are almost a dead give away if you are paying attention. "Seth" is also the name of the ancient Egyptian god of darkness.
* {{Dropped A Bridge On H|im}}er: [[spoiler:Alys]]. And to a lesser extent, [[spoiler:[[StupidSacrifice Nei]]]].
* DualWielding: Possible with every character, starting with ''[=PSII=]'', and highly encouraged when it's not more effective to use a two-handed weapon. You can even dual-wield ''shields'' if you need to beef up a magic user's defense.
* EldritchAbomination: Dark Force in all the games. [[spoiler: The Profound Darkness in ''PSIV'', even more so.]]
* {{Expy}}: There's a reason why Numans seem [[{{Catgirl}} catgirlish]]; Nei was deliberately meant to carry on Myau's legacy. During development, she even had a musk cat's tail. Rika was ''originally'' meant to be Nei herself, as was said by Tohoru Yoshida in an interview; conflict within the staff compelled him to make subtle alterations to keep Rika in.
** In fact, the four main characters of ''PSIV'' are, in a sense, [[FridgeBrilliance representative of the games of the tetralogy]]. Rune Walsh [[spoiler: given his identity as the fifth generation Lutz]] represents ''PSI''. Rika, originally meant to be Nei, represents ''PSII.'' Wren represents ''PSIII'', as another android of the same model was part of the main cast in that game. Chaz himself represents ''PSIV.''
* FightingAShadow: [[spoiler: Dark Force's relationship to the Profound Darkness--especially true in ''PSIV''. Lassic also has a "shadow" fought partway through his castle in ''PSI.'']]
* GenreShift: The jump from classic console RPG to [[MassivelyMultiplayerOnlineRolePlayingGame MMO]] {{Action RPG}} between Phantasy Star IV and the later sub-series, as well as the sidestory text-based adventure games like Phantasy Star Adventure.
* GlobalCurrency: Meseta. One of the mainstay concepts of the series, even after the tetralogy.
* HijackedByGanon: Dark Force/Falz has a nasty habit of appearing in nigh every game in some way, shape or form, [[AvertedTrope except]] ''[[VideoGame/PhantasyStarNova Nova]]'', [[OddballInTheSeries for whatever reason.]]
* HollywoodSilencer: On a laser gun, no less.
* HyperspaceArsenal: As with most [=RPGs=]' inventory systems.
* LegoGenetics: Numans are humanoids comprised of human, monster, and animal DNA. To top it off, the first Numan may have been created ''accidentally''. (Exactly what happened is unclear.)
* LuckilyMyShieldWillProtectMe: Men get traditional shields, while women instead wear emels -- basically thick gauntlets. Unfortunately, in a franchise which offers higher rewards for DualWielding, these are largely useless except on your {{Squishy Wizard}}s.
* MagicKnight: Alis, Rolf, Chaz, and every third-generation protagonist in ''[=PSIII=]''.
* ManaPotion: Many games use Fluids as the magic restoring item. [[AvertedTrope Dropped completely]] from ''Portable 2'' onwards, as the Tech Points system was replaced with the Photon Points system, which serves the same functions, but has a much lower cap and regenerates automatically.
* MasterComputer: Mother Brain in ''PSII.'' [[spoiler:She's got a "daughter" named [[EveryoneCallsHimBarkeep Daughter]] in ''PSIV.'']]
* TheMedic: Amy and Raja are the best examples, and several ''[=PSIII=]'' characters can be turned into this with proper tech distribution.
* NintendoHard: All four games of the tetralogy, although ''PSII'' is the most punishing, even with LevelGrinding.
* OminousFloatingCastle: Lassic/La Shiec's castle in ''[=PSI=]'', Skyhaven and Lashute in ''PSIII''.
* PhantasySpelling
* PlotlineDeath: [[spoiler: Tiem and Nei in ''PSII''. Alys in ''PSIV''.]]
* RedundantResearcher: Subverted.
* RequiredPartyMember: Nei insists on joining Rolf for the first third of ''PSII''. In ''PSIV'', there is even ''less'' options on who to take, as the party makeup is often entirely decided by the plot. Even prior to the final dungeon, four characters in the five-man party are required.
* RobotGirl: Mieu and Miun in ''PSIII'', Demi in ''PSIV''.
* ScienceFantasy: The setting is more or less sci-fi, but magic is commonplace in ''PSI'' and continues to exist in the games set afterwards (though its role is mainly taken over by [[PsychicPowers Techniques]]).
* SeriesMascot: Rappies, [[RidiculouslyCuteCritter little fat fluffy yellow birds]]. It wasn't until ''PSIV'' that they started to fill this role; it's more pronounced in the later games. They also appear in ''PSIII'' by the name "Chirper."
* ShoutOut: In ''PSII Text Adventures,'' Shir's quest involves stealing the [[FantasyZone Opa Opa]], a famous treasure.
** Some of the books Chaz finds on bookshelves in ''PSIV'' also reference other Sega franchises, like ''SonicTheHedgehog''.
* SingleBiomePlanet
** CrystalSpiresAndTogas: [[spoiler:Rykros]].
** GhibliHills: Palma [[spoiler:before its destruction]], and Landen, Draconia, Elysium, and Terminus on the Alisa III... before you factor in their sci-fi elements, of course. Motavia in ''[=PSII=]'', due to terraforming.
** ShiftingSandLand: Motavia started out as this, and is regressing back toward it [[spoiler:after Mother Brain's destruction]]. Also Aridia on the Alisa III.
** SlippySlideyIceWorld: Dezoris, along with Frigidia and briefly Aquatica until Rhys fixes it.
* SortingAlgorithmOfWeaponEffectiveness: Subverted in ''[=PSII=]''. Dezo sells Laconia Daggers for 18,400 meseta, and only Shir can equip them. You'd think they'd be her ultimate weapon... But it only boosts her damage by 4. That's even less than the ''Scalpel''.
** Generation 2 plays it straight thankfully, they've been heavily buffed into being Shir's best weapon.
* SpellMyNameWithAnS: Localization teams lacked consistency with translations (see the CutAndPasteTranslation example above); as an example, the name of the Algo System's planets have ''plenty'' of variations on their names (Palma/Parma/Palm/Parm, Motavia/Motabia/Mota, Dezoris/Dezolis/Dezo).
* SquishyWizard: Noah in ''[=PSI=]''; Hugh and Amy in ''[=PSII=]''; Hahn, Rune and Raja in ''[=PSIV=]''.
* StickyFingers: Shir, ''[=PSII=]'''s resident thief, has a chance of stealing something from every item, weapon, or armor store that the party walks into and taking it back to Rolf's home in Paseo. [[FridgeLogic This includes any stores on Dezoris]], [[ScrappyMechanic which is extremely counter-productive given the circumstance]].
** Allowing Shir to steal something from Motavia's Central Command station nets you a visiphone that allows you to save your game anywhere (through the use item command), but she has to be over level 10 to do it.
* SwordOfPlotAdvancement: Nei Sword in ''PSII'', Orakio's Sword in ''PSIII'', Elsydeon in ''PSIV''
* TalkingAnimal: Myau, and all other musk cats.
* TraumaInn: Averted in the first two games, where you actually visit hospitals to heal your characters and churches/clone labs to resurrect them.
* {{Unobtainium}}: Laconia, a specific mineral found in the Algo star system (typically on Dezoris) which is among the hardest known to man. Your party's best gear will typically include several pieces crafted from it.
** It should be noted that Laconia ''itself'' isn't rare, but the knowledge of how to refine it doesn't get spread around. In IV, several stores sell "Silver" weapons and armor, which one of the shop residents explains ''is'' Laconia, but a low-grade form of it because out of outdated processing techniques.
* UndergroundMonkey: Like other console [=RPGs=], the creatures and enemies found in the tetralogy have lots of cousins, many of them {{Palette Swap}}s.
* ViciousCycle: Dark Force is slated to arrive every millennium to destroy the world.
** Until [[spoiler: A space station slams into Palma in PSII, destroying it, and thus weakening the seal, allowing not 1 but three seperate versions of dark force to slip into their dimension during PSIV]]
* WhenTreesAttack: The trees surrounding Garubrek Tower in ''PSIV'' are carnivorous. There's also a few biomonsters in ''PSII'' that appear to be trees, too.
* YouGottaHaveBlueHair: In addition to blue, purple, and pink, the series has some of the most impossible hair colors ever. To this day, very few video games and anime use a color best described as "electric laser limeade" for hair even once, let alone ''five'' times.
