These games were generally heavily focused on exploring indoor environments, usually a series of small rooms connected by doors, and have distinct adventure and puzzle elements. Japanese developers blended this gameplay style with that of Japanese action-adventure games like The Legend of Zelda to create games like Land Stalker and Light Crusader. This influence later traveled to Europe with Adeline Software's sprawling epic Little Big Adventure, which blended RPG, adventure, and isometric platforming elements.[citation needed]
