While true, it is playable in its EA state,
they are still sussing out marriage and aging. Playing through generations is what I am most excited about, so I pop in to test out their latest updates and such, but I don't play for long spans.
As for how close they are to full release...?
It's coming along nicely, but I'm not quite sure how close the team is feeling to 100%.
They do have a roadmap on their website they keep updated, and if you felt frisky enough to do so you could pop into tge discord.
The devs are quite friendly and generally open to answering questions or just shooting the breeze if you are so inclined.
If you guys like these types of games though, you should check out the kickstarter for One Lonely Outpost. Think Stardew Valley, but you are building up an outpost in space. Space veggies and robo-cows.
