It has got a lot on the way but it is still going to be a significant wait yet. I have my doubts that it will be considered a 1.0 build until 2023.

As for the game currently, it does not have a lot of content. The grinding and searching might set you back tens of hours, but these are tens of hours repurposing a very limited number of assets.
Your replay value may vary. The world is procedurally generated so that no two worlds are 100% the same, but they kind of are. Other than increasing/reducing the time that it takes to travel, all world present a challenge that is 1:1 the same. Fun with friends (but so is poop on a stick), good value for a single solo run, but in this state it only has the same replay value as any other game with building.

It is a good price for what it eventually promises to be. It is an okay price for what it currently is.
