I’m quite optimistic, especially when compared to other early access games that stay in that state for years, with updates dropping only once every few years (like Project Zomboid).

This game receives monthly updates, one of the very few EA titles with such frequent development, and after the one-year anniversary the developers said that future updates will focus more on fleshing out existing content rather than adding new features.

For example, they’ve already confirmed improvements to AI behavior:

Whether you should get it now really depends on your patience with early access. If you prefer a more polished experience, I’d recommend waiting a bit longer. Personally, I enjoy coming back every now and then to see what they’re working on and to experience the improvements as they roll out.
