I started playing pretty early in the last early access and knew it looked like it was going to be good enough to wait things out a bit. And I STILL didn’t make it long before jumping back in. It was apparent that the game was going to end up well done and well polished by watching their completely open design process on their Trello.
These are quite spoiler-y if you haven’t finished Subnautica (Trello) or don’t want to know anything about Below Zero (Favro.)
Here is their main page:
But it looks like they changed over to Favro platform for this dev process.
EDIT: Also being completely honest on my very opinionated view of early access titles, this should be a requirement. Open look at where things are within the plan, throughout the process.
