Lets take a look at this method. Your return value is VideoGame but your return statement is returning videoToReturn which is oof time VideoGame[] which is an array of video games. I believe you over complicated this method. Try changing the contents to return _videoGames; and change the return type on the method to VideoGame[]

public VideoGame GetVideoGames() { VideoGame[] videoToReturn = null; foreach (var _videoGame in _videoGames) { videoToReturn = _videoGame; }

        return videoToReturn;
