Does Sony already have teams helping those 3rd party devs? I honestly don't know. SIE Japan had a significant portion of it's staff that was solely dedicated to doing just that. But Sony completely blew up everything over there deciding to reorganize it all. Much of the staff was let go, with most of the rest to be primarily centered around Asobo studios and first party developed games. So I have no idea what's left over there.
Japan Studio, like Santa Monica on USA or XDEV on Europe had teams dedicated to publishing, localization, brand management and so on 2nd party games for their regions, not 3rd party games. These teams have been merged into a unified, global PlayStation Studios publishing team that also includes their internal 1st party teams. So very likely they will have a bigger budget and resources for future 2nd party games, both western and from Japan.
Now Japan Studio and Santa Monica (not sure if XDEV too, maybe now they are who handle 2nd party on a global scale) are focused on their own internally developed games.
They also downsized the Japan Studio part dedicated to internally developed games and focused it into their most critically acclaimed internal team: Team Asobi, the ones who made the Astro games. They aren't super sellers, but at least unlike the other internal Japan Studio teams they are critically acclaimed and aren't a money sink of huge budgets creating big loses.
183m isn't low? Doesn't a single AAA game costs 100m+?
Either way whatever sony is doing is working so no need to worry
It's an increase of $183M in basically salaries for first party dev studios
in a single year. Means that during this year they will basically double the total amount of people working on their 1st party game development studios. Studios that aren't the ones they have for the HQ, QA, marketing, 2nd party, helping 3rd party, marketing, etc. It's
just for 1st party game development.
The $100M+ budget of a AAA game is the work of a total 1500-2000 people
across multiple years (traditionally 3-7 years). Only 100-300 of these people are from the 1st party game development studios mentioned above, the other ones are external outsourcing art studios, plus internal or external marketing, PR, legal, mocap, audio people, localization, QA, etc.
So you have to split these 100M+ into the different years (let's say 4) and then consider that only a portion of that budget goes to the 1st party game development studio. So let's say these $183M will split into 5-10M for a couple of dozen of 1st party games that would be in the works during this year and would add to what they are already spending on their 1st party studios.
And it's salary for new workers, which means that instead of being a single payment next year they will pay it again and so on.
And remember, it's only for 1st party. They have a separate budget for 2nd party, and another one for 3rd party deals.
TLDR: $100M AAA budget covers multiple years and multiple teams in addition to the 1st party gamdev studio. This $183M is an increase (it adds on top of their current one) only for the 1st party gamedev studios salaries and only covers a single year.
