Like you said if L&P takes a big decision now L&P can complete this game in next 8 to 10 years. because, Already in the game, Sophia is so corrupt that she cheats on her husband. (ex:- last sam bedroom scene event) So, now there is no need for more side characters to corrupt Sophia further. I think this is the right time for L&P to drop some unpopular characters from the game. or add some unpopular characters and storylines to the DLC and L&P can work on this DLC after the main game is complete. isn't it. And L&P can hire a developer for this team and assign them the work of this DLC game. Therefore, L&P can completely focus more on the main storyline of the game. The event of the main game and the event of the dlc game can be given to fans at the same time.
