Despite being nominated for numerous awards and even winning Game of the Year in 2018, the creator of God of War, David Jaffe, is not a huge fan of the new direction the series has gone in. Jaffe himself hasn't worked on these new God of War games, but thinks that they're not staying true to the spirit of the character and the franchise. The creator noted that if developers want to pour their life experiences into their work, they should do it with new IPs and characters.
It may not be the work he wanted, but it was a positive direction. I know nothing about his other works, but new-kratos is a much expanded character and successful continuation on the original work. Not a hamfisted cash-in like so many sequelizations do.
Honestly seeing kratos grow up is what makes the new games that much more impactful. The series when taken as a whole just really makes kratos’s character that much better. Imagine 2018 GoW without the original trilogy, it would not be nearly as close to perfect of a game as it was
The original Kratos was basically one big long revenge story. Almost all of it justified and satisfying, but basically wiping out the Greek Pantheon was his ultimate goal.
His actions were reckless and fury driven, but often went over the top, both in violence and in actions.
My favourite example is from GoW: Ragnarok, when certain characters are reflecting on Kratos’ past, and how the one story of him killing the Sisters of Fate must truly be myth, then he corrects them saying it was true and how they deserved it. The third character then shines a present light on the fact that he did that in the past and says, “that’s the most dangerous and irresponsible thing I’ve ever heard.”
