Here's a more detailed breakdown:

Number of Games:

The GameCube has approximately 552 games released in North America, with a slightly smaller number in other regions like PAL.

Time Investment:

Estimating an average of 5 hours per game, completing all titles would take around 2760 hours.

Factors to Consider:

This estimate doesn't account for factors like:

Varied Game Lengths: Some games may require much more time than others, while some may be completed in much less time.

Game Difficulty: Some games may be more challenging than others, requiring more time and effort to complete.

Breaks and Other Activities: It's unlikely you would play for 115 days straight, so you would need to account for breaks, other activities, and potentially other games.

Non-Retail Games: Some GameCube titles are not sold in retail, but are still considered "games" for the console.

Potential Challenges:

Finding Copies: Depending on the region and specific titles, some games may be difficult or impossible to find, especially those that were less popular or region-specific.

Collecting and Organization: A complete GameCube collection could be a large and challenging collection to organize and manage.
