I don't thing i understand what i am being asked to do.

I have added a GetVideoGames method that accepts no parameters and returns _videoGames. I am confused as to how i am suppose to assign _videogames a value i think. should there not be logic to figure out which game is being picked? how can i do this without passing in a value? What am i not getting? here's my code. Thanks!

VideoGamesRepository.cs 
using Treehouse.Models;

namespace Treehouse.Data
{
    public class VideoGamesRepository
    {
        // TODO Add GetVideoGames method
        public VideoGame GetVideoGames()
        {

                return  _videoGames;
        }

        // TODO Add GetVideoGame method

        private static VideoGame[] _videoGames = new VideoGame[]
        {
            new VideoGame()
            {
                Id = 1,
                Title = "Super Mario 64",
                Description = "Super Mario 64 is a 1996 platform video game developed and published by Nintendo for the Nintendo 64.",
                Characters = new string[]
                {
                    "Mario",
                    "Princess Peach",
                    "Bowser",
                    "Toad",
                    "Yoshi"
                },
                Publisher = "Nintendo",
                Favorite = true
            },
            new VideoGame()
            {
                Id = 2,
                Title = "Mario Kart 64",
                Description = "Mario Kart 64 is a 1996 go-kart racing game developed and published by Nintendo for the Nintendo 64 video game console.",
                Characters = new string[]
                {
                    "Mario",
                    "Princess Peach",
                    "Bowser",
                    "Toad",
                    "Yoshi"
                },
                Publisher = "Nintendo",
                Favorite = false
            }
        };

    }
}
VideoGame.cs 
namespace Treehouse.Models
{
    // Don't make any changes to this class!
    public class VideoGame
    {
        public int Id { get; set; }
        public string Title { get; set; }
        public string Description { get; set; }
        public string[] Characters { get; set; }
        public string Publisher { get; set; }
        public bool Favorite { get; set; }

        public string DisplayText
        {
            get
            {
                return Title + " (" + Publisher + ")";
            }
        }
    }
}

The function body is correct. It will return _videogames but does not assign it any value.

The issue preventing compilation is a type mismatch between the function declaration and the returned item. The _videogames field is an array ("VideoGame[]") but the function shown above is declared to return a single item ("VideoGame").

You currently are not specifying a return type for your GetVideoGames() function.

Take a look at the return type for "_videogames"; it's returning an array "VideoGame[]". Your "GetVideoGames() function needs to have the same return type "VideoGame[]" in order to "return _videogames;".
