My friend, it is unlikely that any game is finished in this industry these days. Out of a hundred projects that get past concept and go into production, only fifeteen will hit store shelves.
As far as the storyline goes, for the most part it has not been decided yet, except for X-Box release. VU is pressuring the team to go with the new-spin garbage, something that all of us are fighting tooth-and-nail, but their position is understandable since they are producing this new snooze-series on Sci-Fi.
The biggest twist is that they changed the origins of the Cylon Mechanicals. Instead of being created by the Cylon race, they are now created by humans. Like Starsiege in space. I hate the idea, and not just because I wrote for Earthsiege/Starsiege and feel that our ideas are being ripped off.
