Mario Kart World introduced an open world where all tracks coexist, enhancing gameplay with connecting roads used in Grand Prix and Knockout Tour mode, yet potentially diminishing the uniqueness of individual tracks.
Let me start with something I like. Borderlands 4 is a vast, beautiful sci-fi game... Exploration, the hunt for quirky optional fights or hidden (hopefully red) chests has been greatly enhanced.
The sheer variance in the story depending on choices creates a unique gameplay experience, where different NPC reactions and boss fights enhance the narrative.
