It seems to be as though you may be seeking reward from the wrong places. Yes you weren't treated great and yes you didn't become part of the team, but you WERE part of something special. The work you did there contributed towards 2012's most successful video game! If you really want to be part of a team you should push for a permanent position somewhere.

On the other hand... if you're confident you're dang good at what you do and don't need to seek outward approval (from the wrong sources) keep being a contractor, keep blasting those projects and eventually someone will notice how you're a common denominator of success.
