Why can’t you use reception methods?

From Go to documentation on method declarations :

The receiver type must be of the form T or * T, where T is the type name. T is called the base type of the receiver, or simply the base type. The base type must not be a pointer or interface type and must be declared in the same package as the method.

Can someone give me some idea of ​​why this might be? Are there other (statically typed) languages ​​that will allow this? I really want to define interface methods, so I can treat any instance of this type of interface as another. For example (steal an example from a Wikipedia article on a template method template ) if the following were true:

type Game interface {
    PlayOneGame(playersCount int)
}

type GameImplementation interface {
    InitializeGame()
    MakePlay(player int)
    EndOfGame() bool
    PrintWinner()
}

func (game *GameImplementation) PlayOneGame(playersCount int) {
    game.InitializeGame()
    for j := 0; !game.EndOfGame(); j = (j + 1) % playersCount {
        game.MakePlay(j)
    }
    game.PrintWinner()
}

I could use any instance that implements "GameImplementation" as a "Game" without conversion:

var newGame Game
newGame = NewMonopolyGame() // implements GameImplementation
newGame.PlayOneGame(2)
