// wrong
var playerRooms = function(id){
  client.hget("player_" + user.id, "total", function(err, rep){
    if (parseInt(resp) >= max_rooms && max_rooms > 0) {
      return false;
    } else {
      return true;

// should work
var playerRooms = function(id, cb){
  client.hget("player_" + user.id, "total", function(err, rep){
    cb( ! (parseInt(resp) >= max_rooms && max_rooms > 0) )
