The phrase refers to the action of acquiring a version of a video game that explores the concept of multiple alternate realities within the Mario universe for use on a personal computer. It suggests obtaining the game files necessary to run this type of fan-made or officially released content on a PC.
The demand for such downloads stems from a desire to experience unique interpretations of familiar characters and environments. The presence of modified games or fan creations showcasing this concept can provide novelty and creative gameplay experiences not found in official releases. Exploring the impact of alternate realities on a established franchise like Mario offers both players and creators a playground for imaginative storytelling.
