What Really Makes a Game Open World?

What really makes a game open world? In this video, we break down the true definition of open-world games, once and for all. From Skyrim and The Witcher 3 to Assassin’s Creed II and GTA V, we explore what qualifies as open world, what doesn’t, and how terms like semi-open world and sandbox actually differ. Using research from Gameopedia and academic studies, we define the genre through the GameTyr Definition, a simple, player-focused way to understand what freedom and exploration truly mean in game design. Whether you’re an open-world veteran or just curious about how these worlds are structured, this video explains it all, clearly, deeply, and without the confusion.
