Time to kick start the community with a question! This is very self explanatory. It's the main reason you're on this sub after all! What is the main reason for liking old Astroneer over the newer versions? Why do you feel more attached to this version of the game compared to the newer version?
For me personally, I liked the storms and the limited rocket range. I always felt like I'm attached to my base, and I don't feel rushed or detached at all from the game when playing. The lighting and the color pallet for the planets are probably the best. They felt very alien, mysterious, and desolate, exploring them was always very fun.
There wasn't a story, nor was there achievements you had to achieve. It was up to you for the reason why you were here and what you wanted to do, not up to the game.
Those are pretty much the only things I can think of at the top of my head, there are many more things I would prefer in the early versions than in the newer ones. But this post is for YOU, what are your reasons for choosing these versions over the newer versions (e.g 1.0 and over)?
I honestly hadn't noticed the recent versions having much of a story. =X
That said, it may be a good idea to have a pinned post/guidance in the sidebar for how to access the old versions for those interested!
