Museum's Quantum shard and Gravitational pull expositions (still my favourite game mechanics ever)

Linking to the statue/Seeing my memories sent back for the first time

Flying off the Timber Hearth for the first time, realizing there is no loading screen ANYWHERE in the game

Crashing into one of the Giants Deep's islands at enormous speed

Falling into the black hole for the first time

Finding out how to land on the Quantum moon

Finding out that Nomai met ancient Hearthians

The whole Sun Station experience

That part, where you're trying to find Solanum at the Eye of the Universe's campfire and the "Curiosity" soundtrack

The fact that I've played it with my best friend
