Zend Db DependentRowset Magic Method - php

Question

I'm trying to use Zend Db findBy() magic method, but it gives me this error:
Application error
Exception information:
Message: File "Game.php" does not exist or class "Game" was not found in the file

Request Parameters:
array (
'controller' => 'game',
'action' => 'platform',
'x' => '2',
'module' => 'default',
)
Seems like it doesn't detect Game.php even though it exists inside /application/models/DbTable/Game.php
Are there any rules or exceptions I am missing?
This is my code
public function platformAction()
{
// action body
$platform = intval($this->_request->getParam('x'));
$platformTable = new Application_Model_DbTable_Platform();
$xbox360 = $platformTable->find($platform)->current();
//$games = $xbox360->findDependentRowset('Application_Model_DbTable_Game');
$games = $xbox360->findGame();
if(isset($games))
{
if(count($games)>0)
{
foreach($games as $game)
{
echo "{$game->name}<br />";
}
}
}
}
