Fudge! Best part about this forum (beyond all the killer help...) is you need to really think about your question in order to post it. And then, you usually solve it yourself!
Turns out I should have been calling the Player model first not the PlayedGame.
This works;
$players = Player::join('played_games', 'players.playerId', '=', 'played_games.playerId')
->where('played_games.game', '=', $request->id)->get()->lists('full_player', 'playerId');
dd($players);
Thanks if you even got to reading this...
