Well, after 101 hours of playtime, I think I can say that I have encountered a lot that the game has to offer. Including all its bugs and limitations. It is still a big "yes" for me. Let's go over a few things.

First off, it is an early access game, and it shows in many ways. Just like many other games, this one has bugs and annoyances. I encounter most of these bugs in co-op games or in mechanics that, I think, need to be reworked or at least fixed soon. For example:
- The game has sound issues when in a co-op game. There are missing sounds if sounds would overlap. Like running makes a sound, and plucking plants makes sounds too, but the later just doesn't play sometimes. Or gun sounds are missing if behind the character that is shooting. The most annoying sound issue is characters keep shouting there are no more creatures around. Even if out of battle for a while.
- Rails have issues, there is a three-lane and a five-lane rail, I haven't used the five-lane rails yet, but the three-lane rails seem to handle items poorly. Especially when rebuilding and reconnecting rails. I am not sure what is causing this obstruction. The line just stays empty while connected from point A to B. A rework of the rail-system is the only fix. To me it seems to be possibly related to another annoyance in the resource mechanic that transfers resources from A to B. As soon as the item leaves Point A, Point B needs to be available uninterrupted and unchanged for the item to reach it. If you were to put a storage in between points A and B, the line stops moving.
- Graphical issues happen often, especially in Co-op. Windows and doors get blinded, sometimes from two square floors away, and this is close by. Windows or doors disappear sometimes in bigger builds. Placing windows in a base in a co-op game, without the host being near the habitat, creates duplicates and messes up the construction. Removing every window needs to be done twice. The host needs to be near to be able to place the windows connected.
- Biggest annoyance in co-op is that the map doesn't get synced with the players.

Those are several of the many bugs in the game. However, these bugs, are not game-breaking (so far).
The game has a lot of fun elements to offer and these are the reasons why I recommend the game.

Building your factory is fun and can be challenging. I think the expansion of your base and factory is at a good pace. The first few levels go quick, and you'll soon find yourself building bigger and bigger. The complexity comes when the more advanced buildings come in play. The whole factory part is very much comparable with Satisfactory, where you build your base, expand and shoot items into space to progress. StarRupture offers a similar way to progress but with multiple companies to choose from, each with their own unlocks. Figuring out on how to reach the next step is what makes base-building fun.

I do miss some structures, this game has a base-defend mechanic that starts after upgrading your core to level 2. Defensive structures are a bit limited, for example there is no wall to put around critical parts, just like in Factorio. Upgrading your base brings in the waves of vermin. Before that, you have the occasional critters coming in to annoy you, but they are easy to deal with. I have not upgraded my core, because I am trying to find the best defence method for the waves, and I have been exploring the map in multiple save-games in Co-op and Single player.
Setting up a defendable base seems logic to me, but that is my playstyle.

The creatures, or vermin, are really fun to deal with. Running around the map, gathering plants, exploring structures and just admiring the surroundings, are not done without fights. The more you explore, the further you go from the starter area, the more intelligent the vermin seem to be. My friend and I have seen them ambush us multiple times. At first you see 2 to 4 vermin close to you, staring at you and then walk away. If you run after them, they start attacking and soon you'll find yourself surrounded by all kinds of vermin on all sides. This creates exciting moments that give a good changeup from the exploring and base building.
If it comes to the vermin, I would like to see them spawn in more. Especially at certain locations, they just don't come back. The goliath vermin, which seem to be the biggest ones, are fun to fight. They are scary at first and they have a killing attack, but with the right strategy, they are easy to kill.
Running around a lot make the vermin seem less threatening. Running into them creates excitement but no real danger. There are moments where they will overwhelm the player(s), but they are manageable.
My friend and I never got killed by the vermin. Except for the first time my friend encountered the goliath.

The waves of the Rupture are insane but easy to prepare for. The wave is an incineration of the whole planet. If you're outside, you'll die. Simple as that. As long as you are able to build a core and a habitat, you'll be fine. My friend and I had one moment that was cutting it close. We ran into a large amount of vermin including a goliath, the wave announcement just came in, and we started building the core with the second warning. Which leaves you with about 25 seconds to get inside. Mind you, we were still fighting too. But these moments is what makes the game so fun.

We are now at a point where we have gathered all necessities to progress the game. We haven't been inside the big structure on the planet, and we haven't upgraded the cores. These are the next discoveries to do. So far, we had a ton of fun, especially when exploring.

The game is certainly worth the price and time. My friend and I wonder often on how the game would be developed, on the things to come. The map is already big, but it is clear that there is a lot more area to be unlocked later on.

A small wishlist would contain the following:
- More structures for defending the base (walls, firepower, defences)
- More resources or levels for the base
- More creatures to fight
- Farming (foods)
- Recycler for certain items (to recover recourses)
- Ability to create, merge, destroy LEM.

Well, I can only say, buy this game. Based on my experience with Green Hell, this game will be amazing too. I've played Green Hell from early EA and it is still one of my favorite games to play. I expect the developer to put the same kind of love in developing this game, it can only become a new favorite.
