Full description: "Dungeon Master (DM), developed and published by FTL Games, is a groundbreaking 3D realtime action role-playing video game that hit the market in 1987. Unlike the traditional turn-based strategy games common at that time, DM brought an immersive realtime experience to gamers worldwide. The game stands out with its unique sound effects indicating the proximity of creatures and primitive dynamic lighting that enhanced the gaming atmosphere. The game deviated from the abstract Dungeons and Dragons style, instead opting for a system where characters' skills improve directly through usage. While not the first game to incorporate these features, Dungeon Master popularized them, setting a new standard for role-playing video games. The game's fascinating mythology and storyline, penned by successful novelist Nancy Holder, also contributed to its wide appeal. Despite being challenged by various clones over the years, Dungeon Master remains a unique gem in its genre.
