Hottest free "open world" games

In open-world video games, the player can move freely through the game world with minimal restrictions. Unlike linear gameplay, open-world design allows players to approach situations in multiple ways, encouraging exploration and creativity. While often associated with RPGs like Skyrim or the Ultima series, the open-world formula can also be found in shooters, action-adventure titles, and even platformers—especially within the metroidvania subgenre.
