GS: Will the player's progress through the game be linear, or will there be opportunities to explore and attempt subquests?

JB: Beside the nonlinear main storyline--which not only has different endings for the characters, but also has multiple endings according the way you play--there are an unlimited number of computer-generated subquests, so the game will never get boring unless you don't like the game itself. Once you finish the main missions, you are still able to play subquests.
