Quoted from mesmashu:

Stern should really look into Agile development and get a scrum master.
Get the entire development team working together and not in silos. Design and plan games together and build a feature set. Determine what needs to get done for launch. Heck you might even sell the game unfinished, but the code that is there is rock solid and bug free. You could sell the game at a cheaper price with base code then people could buy new feature packs. If a game doesn't sell well, maybe you don't finish all the features that were planned but the game is still solid and may have a simple rule set like Iron Man.
This would allow ops to get a game at a cheaper price and not have to pay for features most route games will never see. They can turn around and sell the game to a newcomer at a low price and they will have the option to buy more features for home use.
