You don't need a loop.

The error message is complaining that the method doesn't return anything if the loop ends or doesn't run. But you don't need a loop here anyway. All the task 1 method (GetVideoGames plural) needs to do is just return the static field with the entire collection.

You'll also need to modify the return type in the method declaration to match the type of the field.

The method you will build for task 2 (GetVideoGame singular) will be a bit more involved.
