The thing is Japan Studios was like 6 different studios and they were all super unorganized and inefficient. Restructuring means basically trimming a large portion of fat and reinvesting in the most efficient of those studios.
The way i see it is, Japan Studios felt more like a large support studio/incubation studio. From what i read they had liek 15 different projects in various stages that would just never come to fruition because it was all managed really badly. Games would be pitched, start production and cancelled, one after another which is why we barely got anything in the last 5 years of the PS4’s life cycle.
It was a big battle royal to see which studio would come out victorious and after Team Asobi put out two successful projects in a genre sony desperately lack in it was clear they would win the title. Team Asobi can put out high quality games on a timely schedule which is the most important aspect of any of their studios. Not only do they serve a niche but they are multi-talented, in both standard tv and VR.
With the ICO team we’d still be waiting on their next game, for years. Only for it to possibly not even sell well again. With Bokeh/Project Siren team we’d be waiting on Slitterhead which honestly doesn’t look great either.
Make Team Asobi a two team studio and it’s already a far better studio than Japan was
