The issue here is that the declared return type (a VideoGame[] array) doesn't match what the function actually returns (just one single VideoGame object). Fix that, and you'll pass the challenge.

Ive tried it and it didnt seem to work

I copied your code into the challenge, and it passed after making this one change to line 13:

        public VideoGame GetVideoGame(int id)    // VideoGame instead of VideoGame[]
