These two fairly different games have one thing in common in their testing procedures, they involve the public. Others have pointed out that other companies do that as well with varying degrees of success. SE could utilize this approach as well but it would take a change in development philosophy. From what I have seen in both FFXI and XIV Square uses a very closed development system and it has hurt them many times.
