It's an asynchronous call.

If you log it inside the callback, it shouldn't be empty:

playingCollection.find({},function(err, companies) {
    companies.each(function(err,company){
            if (company !== null) {
                var obj = company.playername;
                state.push(obj);
            }
        }
    );
    console.log(state); 
});

Use toArray

playingCollection.find({}).toArray(function(err, companies)
