If you want the rating link to display again,

open arcade.php
locate the following at round line 2460

            if( $this->arcade->user['id'] != 0 && !isset($raters[$this->arcade->user['id']]) )
            {
		//no rating here, play game to rate!
//                    $rating .= $this->html->rate_link($the_game['gid']);
            }

Remove the // before

 $rating .= $this->html->rate_link($the_game['gid']);
