The early-mid game is one of my favourite gaming experiences of all time. It's usually the most part of a survival/crafting game, but I was surprised by how well Subnautica was peppered intrigue.

As you and many others on this thread have said though, a mobile port seems odd. Even if the UI were reworked, I can't imagine that players would be able to feel the same sense of awe that I associate with the game.
