What was the worlds first RPG video game?

The title of "world's first RPG video game" is a bit of a debate, as it depends on how you define "RPG." Here are some contenders:

* Dungeon & Dragon (1974): While not a video game, this tabletop role-playing game is often considered the "granddaddy" of RPGs. It established many core RPG elements like character creation, dice rolls, and narrative storytelling.

* Colossal Cave Adventure (1976): This text-based adventure game was a massive hit and is considered the first true computer RPG by many. It featured a rudimentary form of character progression and exploration.

* Zork (1977): Another text-based adventure game, Zork further refined the genre by incorporating puzzles, inventory management, and a more complex world.

* The Wizardry (1981): This game, which popularized the term "RPG", featured dungeon exploration, turn-based combat, and character development systems.

* Ultima I: The First Age of Darkness (1981): This game is considered the first true "role-playing" game with an open world and a focus on narrative. It also introduced the concept of a "party" of adventurers.

Ultimately, the "first RPG" is subjective and depends on how you define the genre. But all of these games played a significant role in shaping the RPG genre we know and love today.
