Hideo Kojima recently polled fans on their favorite Death Stranding 2 trailer, and obviously, the winner was Higgs. But while Troy Baker's villain came out on top, he didn't run away with the votes. Kojima himself is pretty happy about that, since he's been pouring his heart into character creation for years and can now rest assured that all his children have their fans.
If you've stumbled upon Tomorrow's Nightmare in Death Stranding 2, you've already been asked to choose between Higgs, Rainy, Fragile, and Tomorrow. The game doesn't really present any criteria for the choice, simply imploring you to "choose well." Are you meant to pick your favorite character? The one you'd like Sam to become romantically entangled with? (That would be weird for a lot of reasons.) The one you feel the deepest spiritual connection to? That's for you to decide.
