''Lagoon'' is an ActionRPG created by Creator/{{Zoom}} for the SharpX68000 in 1990 and published for the {{SNES}} by KEMCO in 1991. The SNES version is the more widely known, due to the greater popularity of the system and the availability outside Japan. Most of the following pertains to the SNES release.

The game follows the journeys of Nasir, Champion of Light, as he fights to restore peace to Lakeland.

The prologue unfolds in a series of short animated scenes, followed by a briefing by Nasir's long-time mentor Mathias. It seems the water of Lakeland, which flows from Lagoon Castle, has been getting muddy recently. Mathias sends you to Atland, and the adventure begins. Nasir must fight his way through a series of areas defeating the forces of evil while meeting new friends and unlocking the mystery of his origins.

Lagoon plays like a hybrid between the ''VideoGame/{{Ys}}'' series and ''Franchise/TheLegendOfZelda'' series, using a similar leveling and control system to the former with the pseudo top-down perspective of the latter.

The original X68000 version of the game featured more side-quests than the SNES version, but the SNES version features a more flexible Magic system and additional supporting characters. The music in certain areas was changed between versions as well.

!!Tropes featured include:
%% The game is listed on CuteShotaroBoy, but I can't figure out from that page whether the actual example is Nasir or Thor, so somebody who's played the game is going to have to add it.
* AnEconomyIsYou
* AwesomeButImpractical: Most of the higher level magic attacks
* CainAndAbel: Mild variation combined with LukeIAmYourFather regarding Nasir and Thor.
* ConvenientQuesting
* EscortMission: As your first real ''mission''. It's rather sweet, considering how easy it is for you to die...
** Not that dying is the real problem regarding this escort duty; the person you must find and bring back to town has an injured leg and therefore will move to a painfully slow pace. On the other hand, enemies cannot hurt him.
* ExpositionBreak: Occurs a few times throughout the story.
* FakeDifficulty: Your sword is the size of a toothpick. The enemies are very difficult to hit thanks to the disjointed hitboxes. Oh, and the first Boss can be nearly impossible because he can jump and trap you in continuous damage. [[SarcasmMode Fun.]]
* FlashOfPain: For the player as well as the enemies.
* HeroesPreferSwords: With magic often being AwesomeButImpractical, and downright unusable in boss fights, the sword, stubby though it may be, is the main way to go.
* InexplicableTreasureChests
* InformedEquipment: Averted with armor and shields, played straight with swords, rings, magic, and items (Although the last two get icons indicating what is active)
* InvulnerableCivilians: The first major thing you do is explore a dungeon and do an {{Escort Mission}} with a little boy. He can't be hurt at all, but goes at quite a slow pace...
* IrrelevantImportance: Many of the items have only one use, and stay in your inventory once you are done with them.
* ItsUpToYou
* LockedDoor: Some of which require significant backtracking to unlock.
* MoneySpider: Every baddie in the game gives you a certain amount of gold each, depending on type.
* OneSteveLimit: Save regular monsters, no NPC is repeated. Also, you can only have one of each item no matter what.
* OnlyIdiotsMayPass: Averted with one of the three tablets to open Philips Castle, but played straight the rest of the game.
* PaletteSwap: Averted in the X68000 version, used in the SNES version for Nasir's armor changes.
* PointOfNoReturn: Four of them, in fact.
* RegeneratingHealth: Speed varies depending on what enemies are about: Fast if none are around, regular if regular baddies are around, none in boss rooms.
* [[SaveThePrincess Save The]] [[strike:[[Series/{{Heroes}} Cheerleader]]]] [[SaveThePrincess Princess]] / SaveTheWorld: In that order, but not by saving the princess.
* TitleThemeDrop: For the FinalBattle no less...
* TooAwesomeToUse: Most of the Healing Items, particularly the Shiny Ball.
* UnwinnableByMistake: It's possible to save virtually anywhere as long as you're not in the middle of a boss fight. Even if you're about to fall down a BottomlessPit.
** Selecting the option to save while in motion or midair simply causes you to exit the menu without saving. The projectiles and direction moved for enemies do not get saved either, so it's not possible to save oneself into an unwinnable situation, although you can turn the odds unbearably against you. For instance, you can save the game while surrounded by enemies as you cling desperately to those last few hit points.
* VoiceGrunting: The beeps variety, complete with varying tones for different characters.
