I'll take a shot at how it could be successful.<p>Unions can add value in industries that need vast numbers of highly specialized individuals.<p>If you think of a film or a play, both unionized industries, a production works by hiring a mess of specialists who show up ready to go. Everyone knows what they're doing, why they're there, etc. There's a very good discussion (with a libertarian economist, no less) here[1] about it.<p>There is a large part of game development, especially in the "blockbuster" game development that seems like it fits this model quite well.<p>It might not apply to more specialized elements like game engine design, but for modern games that are designed more like movies than games, it could be highly effective.<p>[1]: <a href="http://www.econtalk.org/mitch-weiss-on-the-business-of-broadway/" rel="nofollow">http://www.econtalk.org/mitch-weiss-on-the-business-of-broad...</a>
