What do you want Sony to do that they aren’t already doing?
Jimbo does not have a blank check
Their revenue has gone up ten fold since the PS2 era. They need to up their investment in their internal first party studios and no i dont mean by acquisitions. Every studio needs 3 teams of 500 people. And they all need to be in 3 year dev cycle. GG, SSM, Sucker Punch, and Sony Bend can no longer take 5 years to make 1 last gen sequel. They need to be at least as productive as Insomniac and at best as productive as the CoD studios who have managed to release a new CoD every year for the last 14 years without ever missing a deadline or taking longer than 2-3 years.
There is simply no excuse for having 100 man teams over at Sucker Punch and Sony Bend. Or 200-300 men teams at GG, ND and SSM. This isnt a mom and pop shop.
It would not require a blank check. Hiring devs does not cost billions. They come very cheap. ND games in the PS3 era used to cost $20 million when they had 150 person teams making games on a 2 year dev cycle. Even 5 $100 million games from their five internal first party studios every year is pennies compared to what MS just spent on one game per year.
What can Jimbo do different? Dont port your precious IPs to Microsoft's platform for once. Dont waste your time porting games when you can be putting extra resoruces getting games like Horizon out in 2021. If he can hire a studio to port Days Gone, GOW, Horizon and uncharted to PC then he can hire them to help GG, PD and SSM to ship in 2021.
And lastly, Apple made their name by producing the iPod, high end iMacs and of course the iPhone. They were at the forefront of technology. They didnt give a fuck how much they cost. They wanted the latest and greatest tech knowing people would pay top dollar for it. Horizon, GOW and GT7 being cross gen is dated tech and they will not convert any fence sitters into buying their games and consoles.
