I personally think that they should follow the character of Hercules in upcoming games. He was an excellent opponent in the game and it was very fun to fight agianst his brute strength. But obviously if you played through the game you would know that this character could not be played in sequels. So I thought that prequel games would best fit Hercules. Before you fight him he mentions his 12 labors and how Zeus always favored Kratos. This to me sounded like an opening for a prequel game. But instead of just playing in the past you could also play as him at the start of the second great war. Since most of the Titans just disappeared in the game seeing Hercules' point of view of the second great war would also allow you to see how the gods disposed of the Titans and this will lets you interact with the Olympians and fight with them before they are picked off by Kratos.
Most importantly of all if any of you watched the videos available after the game is finished you will notice that the Original Hercules

That is my opinion on which direction the GOW Franchise should take what do y'all think?
