''Evolution: The World of Sacred Device'' (known as ''Shinkisekai Evolution'' in Japan) is a console role-playing game for the UsefulNotes/SegaDreamcast. It was developed by Creator/StingEntertainment and published by Ubisoft in North America and Europe. In Japan it was published by ESP (Entertainment Software Publishers). It also had a downscaled port for the UsefulNotes/NeoGeoPocket titled ''Evolution: Eternal Dungeons''.

''Evolution'' is a DungeonCrawling game that follows the adventures of Mag Launcher and Linear Cannon. Mag Launcher and his companions use Cyframes (minus a few), technology discovered in ancient ruins. These Cyframes are sought by adventurers who explore caverns to find them.

Combat in ''Evolution'' uses PreexistingEncounters and enemies appear only in dungeons. The battle is turn-based, using three characters. One of the major things that makes this games battle style different is the use of Cyframe characters. When using these types of characters they have interchangeable parts for their weapon (which cannot be unequipped) to give them different specials and stats. Not every character can utilize Cyframes and for the ones that don't, they have to level up and learn set skills from their list.

This game had one sequel, ''Evolution 2: Far Off Promise'', and a UsefulNotes/NintendoGameCube remake, ''VideoGame/EvolutionWorlds''. A novelization of of the first game was also released... [[NoExportForYou in Japan.]]
!!This game contains examples of:
* AllInARow: Unlike future installments, Mag always heads the line.
* AllThereInTheManual: Supplementary material gives off a few more details for the game, such as the characters' ages and zodiac signs.
* ArbitraryGunPower: [[spoiler:Every enemy in TheVeryDefinitelyFinalDungeon. There are even TANKS you have to fight, yet they seem to do as much damage as a normal enemy.]]
* ActionInitiative: Run into an enemy from behind, the music sounds happy and you get free turns to happily punch your enemies. Have an enemy run into YOU from behind, the music gets daunting and you stand still while the enemy beats your head off your shoulders.
* AmericanKirbyIsHardcore: The above is the US box art. [[http://www.gamefaqs.com/dreamcast/197249-evolution/images/box-13766 This is the Japanese box art]], [[http://www.gamefaqs.com/dreamcast/197249-evolution/images/box-103617 this is the EU box art]].
* ArbitraryHeadcountLimit: 3 people max on your team, 4 max on enemy teams, however most bosses come with only one enemy: the boss itself.
* AwesomeButImpractical: Two of Pepper's skills, Trigger Happy and Pepper Flash, can easily do 9,999 damage at high levels, but they both cost all of her FP to use, and their power is linked to her remaining FP.
* BareYourMidriff: Pepper
* BattleThemeMusic: In addition to a boss and final boss theme, the battle music changes depending on the situation of the battle (normal battle, Mag's party has the advantage or the enemy has the advantage)
* CantDropTheHero: Mag is the title character, therefore he must always be in the party and controllable, so you cannot get rid of him whatsoever... Not like you would want to.
** Linear is like this during the main campaign, and must always be in your party no matter what until the postgame. Before the postgame during the TheVeryDefinitelyFinalDungeon, you are required to have at least two other characters in your party at all times, and Mag must be one of them while Linear cannot be for story reasons
%%* CharacterLevel
* CriticalHit: Shown by the enemies having a different hurt animation.
* CuteMute: Linear, except at the end, although she still doesn't talk much.
* DefendCommand: On top of reducing damage, it increases the amount of SP restored.
* DisappearedDad: Mag's father, Asroc Launcher.
* DiscOneNuke: Mag's hand parts, which you have at the start. By gaining TP you can learn two really strong attacks pretty early: Dive Punch, which hits every enemy doing lots of damage) and Magna Rave, which hits one enemy but is the strongest attack in the game.
* AnEconomyIsYou: Where are people supposed to buy food in this town?
* EndgamePlus: You get one bonus dungeon (which is one of the five you didn't pick during the game), able to freely choose dungeons and the ability to take Linear out of your party.
* ExperiencePoints
* FingerlessGloves: Both Mag and Chain wear these.
* GlobalAirship: Mag's Sea Otter Seaplane can get him to anywhere.
* ImprobableWeaponUser: Linear's FryingPanOfDoom. Even made worse if you unequip Gre or Linear's weapons, making them run up and punch the enemy with their bare hands.
* InexplicableTreasureChests: There's a large number of chests containing healing items, the same artifacts over and over, and an inexplicably large number of Cyframe parts that your friends can easily use.
* LethalChef: Gre uses food to damage enemies and lower their stats or cause status effects.
* LethalLavaLand: The Sheol ruins is located inside of a volcano, complete wit lava in the upper floors.
* LevelScaling: This can be the games biggest helping point or massive flaw depending on how you look at it. The bosses scale much faster than the player, and the final boss, Eugene's battle mech, is the biggest threat, the higher level you are the more impossible he is to beat, and he will always be above your level.
* LightningBruiser: Mag is easily the swiss army knife of your party. He dishes out great damage, gets very good skills and cyframe parts (more than any other character), can even gain healing parts, and easily makes up the best part of your team no matter what. It's ironic considering he's required to be in the team at all times.
* MsFanservice: Pepper. Half ripped jeans, curled blond hair, jacket ripped open showing a black bra, and her theme music which is saxophone music.
** Another girl in town is implied to be naked. Though no skin is seen every dialogue with her speaks directly about the fact that she's wearing nothing but a leopard print fur coat until her luggage arrives. Makes you wonder why she was only wearing the coat by itself in the first place.
* MysteriousWaif: Linear. You never get a full explanation as to what exactly happened to her or why she's mute in the game, but she certainly has a lot of mysterious air about her.
* OneManParty: Mag is easily the strongest character. The other characters levels will appropriate to what level you are, but Mag always seems to have the edge in strength.
* OnlyInItForTheMoney: If you do a mission with just Mag and Linear, your entire win bonus goes straight into your pocket. If Gre is in your party, he'll make you use 30% of your bonus to pay towards your debt (which you should do anyway so you're not losing anything) and after it's paid off, he'll never make you do anything with your money again. Chain, on the other hand, takes 30% of your bonus for herself, and Pepper takes 60%. The worst part, you never get this money back, so it's basically losing massive chunks of change for having people in your party. If you were to net an incredible 100,000 in the game and had Pepper in your party, you lose 60,000. The worst part: bonuses are a one time thing, going back and beating the dungeon again means nothing, the money is gone. You'd think they'd have it at least available for item purchase but nope, Mag's gotta spend his cash on Naolin's and Red Viper. It pretty much makes it not worth taking them at all for any stage, or swapping them out just at the boss fight for either Gre, or just Mag and Linear. It doesn't matter anyways, they scale to your level and gain TP for fights despite being back home.
* OverlyLongFightingAnimation: Magna Rave and Sledge Hammer.
* PointBuildSystem: You can gain TP in the game, which can be used to learn new skills.
* PunnyName[=/=]ThemeNaming: Mag Launcher, Linear Cannon, Gre Nade, Chain Gun and Pepper Box. Makes Eugene stand out.
* RequiredPartyMember: Linear. She cannot be dropped from the party until the final dungeon, when she's forced out. After the final boss, she's no longer required.
* RunDontWalk: Though they had a button to walk, it isn't needed and doesn't do anything.
* SavePoint: located in certain spots in town and on the final floor of a dungeon.
* SmugSnake: Prince Eugene
* SpaceZone: The Descent Ruins, on the latter floors, have a cosmic theme, with stars in a void.
* ThrivingGhostTown: There's only about 10 NPC's and the majority are useless. Except for the shop owner, upgrade shop, missions, and appraisal, everyone else does nothing whatsoever except talk about totally irrelevant things or mention stuff you already know.
* TooAwesomeToUse: Cosmo Fruit.
* TopDownView:
* {{Tsundere}}: Chain. This is even mocked at the beginning of the game when she begins making fun of Mag until Mag embarrasses her with the word cute, at which point she tries to defend herself but just takes off flustered.
* WhiteMage: Linear, has tons of magic attacks and only two are attack.
* WikiRule: [[http://evolutionworlds.wikia.com/wiki/Evolution_Worlds_Wiki Here it is]].
* WorkOffTheDebt: Both Mag and Chain were left with a huge debt after their parents disappeared. Chain paid it off by selling her house, while Mag is playing this trope.
