Jaffe always struck me as a perpetual adolescent. The two GoW games he worked on were great for the time, but the stories were shallow excuses to showcase as much gore as possible. His other big property, Twisted Metal, was genre-defining gameplay but any narrative was just edgelord violence and/or crass humor.
The last “big” project I remember coming down the pipe from him was Drawn to Death, which took his signature juvenile tastes and combined them with horrible gameplay and eye-blistering art direction. As far as I’m aware, he hasn’t worked on a game since.
I’m not saying the new GoW games are perfect, but I wouldn’t say Jaffe has a trusted critical eye.
I think that’s more about WotC giving up on cons and tourneys than giving up on artists. If they’re having events at all, they’re not putting as much money into them as they used to.
I always figured this was an intentional part of the design philosophy. The game lets players write and read one- or two-sentence strategy guides anywhere in the world. I took the hint and figured they wanted me to look up strategy guides.
