Get eloquent model from DB including sub models

I'm learning PHP and the Laravel framework and i'm getting stuck on loading some data from the database.

I have 2 models, Game and Player

Player model (curently empty):

class Player extends Model
{
}

Game model:

class Game extends Model
{
    public $Players = [];

    public function __construct(array $players = [])
    {
        $this->Players = $players;
    }

    public function SaveGame()
    {
        if($this->save()) {
        Log::info("New game created with id " . $this->id);
        }
        foreach ($this->Players as $key => $player){
            if ($this->Players()->save($player)){
            Log::info("player added to game with id " . $player->id);
            }
        }
    }

    static function GetGame($gameId)
    {
        Return Game::find($gameId);
    }

    public function Players()
    {
        return $this->hasMany(Player::class );
    }
}

And i have a GameController:

class GameController extends Controller
{
   public function create()
    {
        $players = [];
        for ($i = 1; $i <= 3; $i++) {
            $player = new Player();
            array_push($players,$player);
        }

        $game = new Game($players);
        $game->SaveGame();

        return $game;
    }

    public function LoadGame($id)
    {
        $game = Game::GetGame($id);
        return $game;
    }
}

If i call the create() method of my GameController, it creates a game in my Game table and 3 players in the player table with the gameID of the corresponding game so i think the relation works fine.

But if i check the response of the create() method i get only this:

{
"updated_at": "2018-03-01 15:13:37",
"created_at": "2018-03-01 15:13:37",
"id": 3952
}

Also the LoadGame() function returns just the game. Actually i need the game with all its players inside. Something like this:

{
"updated_at": "2018-03-01 15:13:37",
"created_at": "2018-03-01 15:13:37",
"id": 3952,
"players":[
       {"name":"player1"},
       {"name":"player2"},
       {"name":"player3"},
     ],
}

What i'am doing wrong?/How do i get the wished result?

I'm also not sure if the Models are the right place to do the database actions and the controllers are the place to create the objects like i do in the posted code. If my "code structure" is not the best practice, some advice in this is also welcome!
