''Dragon Slayer'' may look archaic to modern players, but back in 1984, when it was first released on the [[UsefulNotes/{{PC88}} NEC PC-8801]], many players must have agreed with the intro screen which proclaimed it to be "a new type... unlike any other game you have played on your computer." For this, ''Dragon Slayer'' was one of the very first {{Action RPG}}s, and it set the precedent for many future games in the genre by Creator/{{Falcom}} and other companies.

The concept of role-playing in ''Dragon Slayer'' is quite rudimentary: there are no [=NPCs=], and the player character appears to be a generic adventure hero. The game consists of tile-based levels called "phases." In each phase you start out at your house, wandering around trying to find first a sword, then coins, potions to increase magical power and various useful items which can only be carried one at a time. You can gain experience from fighting the endless waves of increasing tougher monsters, which eventually lets you use spells and move diagonally but does not make you stronger in combat. What does increase your strength is finding orbs by unlocking chests and bringing them home one at a time. The objective of each phase is to kill the dragon's three heads and recover the four crowns it guards.

Ports of ''Dragon Slayer'' were made for various systems, with many of the monsters redrawn as entirely different creatures. The UsefulNotes/{{MSX}} version was produced by Creator/{{Square|Soft}} in their pre-''Franchise/FinalFantasy'' years. The UsefulNotes/GameBoy version was made by Epoch (who had earlier ported it to their ill-fated UsefulNotes/SuperCassetteVision console); this version was the first to feature smooth (but painfully slow) scrolling, and was followed on the same platform by a GaidenGame produced without Falcom's involvement. Finally, a VideoGameRemake for the UsefulNotes/SegaSaturn appeared in the Falcom Classics collection, featuring substantially improved graphics and music and considerably lowered difficulty.

''Dragon Slayer'' was the start of a long series of games. Most of these were {{Non Linear Sequel}}s, bearing as little relation to each other as they did to the original, and many of these games had sequels of their own and later remakes which dropped "Dragon Slayer" from their titles. Therefore, here is a list of all subsequent Falcom games that carried the ''Dragon Slayer'' name:
* ''VideoGame/DragonSlayerIIXanadu''
** ''VideoGame/{{Faxanadu}}''
* ''Dragon Slayer Jr: Romancia''
* ''[[VideoGame/LegacyOfTheWizard Dragon Slayer IV: Drasle Family]]''
* ''Dragon Slayer V: Sorcerian''
* ''Dragon Slayer VI: The Legend of Heroes''
* ''Dragon Slayer: The Legend of Heroes II''
* ''Lord Monarch''
* ''The Legend of Xanadu''
* ''The Legend of Xanadu II: The Last of Dragon Slayer''

The VideoGame/KisekiSeries is a spinoff/SpiritualSuccessor of ''The Legend of Heroes'' series, which began with ''Dragon Slayer VI: The Legend of Heroes''. Two [[AnimeOfTheGame OVA]] series based off of the first couple of games[[note]]a one-off based off of ''Xanadu'' produced by Creator/ToeiAnimation, and a 2-episode series based on ''The Legend of Heroes'' by Creator/NakamuraProductions (with assistance from Creator/AnimeR).[[/note]] were released in 1988 and 1992.

Not to be confused with the 1981 movie ''Film/{{Dragonslayer}}''.
