Splitting Issue 13
The Good: The Mission Architect feature is getting customizable allies and enemies, at the request of the playerbase!
The Bad: This will delay the Mission Architect feature, pushing it back to Issue 14: Architect, which is slated for Q1 2009/Winter.
The Awesome: Issue 13: Power and Responsibility (new name) has some spectacular new feature announcements, and is slated for Fall 2008, with closed beta starting "soon™"!
