The problem is that executives will ask "what makes Stardew Valley successful?" and never make it to this answer:

A developer who genuinely cares about the quality of the game, interacts positively with the community around it, and makes decisions that demonstrate his caring for the game and the community. Specifically, decisions that often leave revenue on the table, particularly in the short term but arguably in the long term as well.

That sort of caring is largely impossible for private equity, and it's really hard to successfully fake.
