Strongly recommend Outer Wilds. Falling into the black hole the first time was one of my most scared moments in gaming. I was totally panicking lol
And getting close to the upper atmosphere of Giant's Deep for the first time, staring, thinking about the atmospheres of real-world gas giants, knowing that I need to take the plunge.
That game exposed some phobias that I'd only been vaguely aware of before.
I recommend the game Exo One then.
It's a surreal game of flying a spaceship around in the atmosphere of a gas giant. While beautiful to look at, I know enough that flying around in a gas giant is so terrifying a prospect I never managed to complete the demo of the game. "Oh, how do you falling through pitch black clouds with winds in the 3000+ km/h where it's raining literal diamonds until you reach a lake of supercritical fluid at extreme pressures?" You don't even have to go very far, there's 4 of these in our solar system alone.
Or when you do a space walk, just kinda pop feet first out of your little ship. Scares the bejeesus outta me
The Outer Wilds is one of the greatest gaming experiences of all time. I would love to forget all about that game to just experience it again from scratch.
Side effects may include overwhelming hate for Walt Disney Productions.
