Are any of them Japanese? Or based in Japan? You'll quickly find most of the publishers you mentioned have deadlines to meet. No way will he have the same creative freedom and Money Sony will bankroll him with
Zenimax isn't japanese either and Mikami works for them.
And every single publisher has deadlines. Stop. Some give more leeway, that's it. WB is one of those. They delayed Batman AK a whole year. Let Avalanche remake Mad Max from scratch. Delayed Dying Light several times.
All of those games had hude budget (Kojima-like budgets) too.
I mean, i'm not disagreeing that Sony is great with that. Just that i wished he would go third-party. I don't really like any creators locked up to a single console, but if it's the only way for him to make games, that's ok.
