This DLC got mixed reviews at launch, so I waited until the developer made some updates to address the initial feedback. With the recent updates, I think they succeeded because I found this a great DLC--both fun to play and a good value (i.e. hours played per dollar spent).
Keep in mind this is not a sequel. There's a couple new things (e.g. rock crushers), but it's basically the base game with a new planet. Humble is much more rocky and hilly than the base planet, which made it feel both different and more challenging. The developers claim the planet is 1/2 the size of the original, but it still feels huge. Resources also felt more difficult to acquire than the base game, again adding to the challenge. This seems correct. As a second planet, you assume the players are more experienced and want a higher difficulty level.
The devs also said they wanted players to get that "new world to be explored and discovered" experience again, and I would say they succeeded. Without my maps, jet pack, and gear I was used to, I felt like a novice planet crafter again. I spent my first part of the game exploring to find critical resources while often getting lost and almost running out of water, food, or O2 several times.
My only negative feedback is the game's ending. Or I should say the lack of ending. The DLC has an interesting back-story that you learn about through the usual means. However, it feels like the devs ran out of time and never finished this. There's conflict and rising action, but there's barely a climax and no plot resolution. So, overall, I give the DLC an A- due to lack of an ending and not finishing the story, but I would change it to A+ if they added a proper ending with a climax and a plot resolution.
