edition in 2018.Assassin's Creed, a long-running Ubisoft franchise, also shifted towards the action RPG formula, inspired by the successes of The Witcher 3 and the Dark Souls series, with its titles Origins (2017), Odyssey (2018) and Valhalla (2020). Subgenres First-person dungeon crawl In late 1987, FTL Games released Dungeon Master, a dungeon crawler that had a real-time game world and some real-time combat elements (akin to Active Time Battle), requiring players to quickly issue orders to the characters, setting the standard for first-person computer RPGs for several years. It inspired many other developers to make real-time dungeon crawlers, such as Eye of the Beholder and Lands of Lore: The Throne of Chaos.Ultima Underworld: The Stygian Abyss, released in 1992, has been cited as the first RPG to feature first-person action in a 3D environment. Ultima Underworld is considered the first example of an immersive sim, a genre that combines elements from other genres to create a game with strong player agency and emergent gameplay, and has influenced many games since its release. The engine was re-used and enhanced for Ultima Underworlds 1993 sequel, Ultima Underworld II: Labyrinth of Worlds. Looking Glass Studios planned to create a third Ultima Underworld, but Origin rejected their pitches. After Electronic Arts (EA) rejected Arkane Studios' pitch for Ultima Underworld III, the studio instead created a spiritual successor: Arx Fatalis. Toby Gard stated that, when designing Tomb Raider, he "was a big fan of ... Ultima Underworld and I wanted to mix that type of game with the sort of polygon characters that were just being showcased in Virtua Fighter". Ultima Underworld was also the basis for Looking Glass Technologies' later System Shock. Isometric/top-down dungeon crawler The 1988 Origin Systems title Times of Lore was an action RPG with an icon-based point-and-click interface. Bad Blood, another Origin Systems game from 1990, would use the same interface. The designers were inspired by console titles, particularly The Legend of Zelda, to make their interface more accessible. The 1994 title Ultima VIII used mouse controls and attempted to add precision jumping sequences reminiscent of a Mario platform game, though reactions to the game's mouse-based combat were mixed. In 1997 Blizzard's Diablo was released and became massively successful. It was an action RPG that used a mouse oriented point-and-click interface and offered gamers a free online service to play with others that maintained the same rules and gameplay.Diablos effect
