Larn was an old roguelike game. Larn took inspiration from Rogue and Hack. In the past, Larn and NetHack had contemporary development, and some Larn references entered NetHack. But NetHack continued development and became a popular game with a large community, while Larn stalled. Larn is now an obscure game with few players. The Larn Revenue Service or LRS is the tax agency that seeks to collect from wealthy Larn players.
