Pretty much all we need. Both Sigil and Microsoft are determined to do what they each do best. Both companies tend to let their key partners lead the way in terms of development and design.
Our pitch to Microsoft for Vanguard back in early 2002 was received positively, as have been the design documents and the work and milestones we've completed thus far. While Vanguard: Saga of Heroes as a whole is a team effort, the actual development of the game takes place almost entirely at Sigil, including design, art, and programming.
