  (function(players) {
    var cur_idx = 0;
    function cb(name, err) {
      // just kidding, not going to handle errors!
      if (IsValidName(name)) {
        players[cur_idx].name = name;
        cur_idx++;
      }
      if (cur_idx < players.length) {
        Ask("What's your name", cb);
      }
    }
    Ask("What's your name", cb);
  })(players);

This is of course completely awful. just2n's reply is a nicer realization of the same concept. sprobertson's reply clearly will not work as written, and I don't expect it's even possible to condense this code into a single call to eachSeries.
