Ok, when I run

$leaderboard_q = $DB_site->query("SELECT game,userid,comment,date,max(score) as maxscore
                                    FROM arcade
                                    WHERE game='$gamename'
                                    GROUP BY userid
                                    ORDER BY maxscore DESC
                                    LIMIT $top_number");

in place of the standard leaderboard_q code, I get no records returned.
