After having the played the game just over 200 hours (including mobile hours), I have played through the available content released as of writing. I can only recommend this game.
The main gameplay is a based on a turn based tactical combat system. The narrative and world building of Limbus Company and the Project Moon universe in general is great. Playing the other Project Moon games to understand and play Limbus Company is not necessary. While the events of the other games are referred to a few times in Limbus Company, it is done so without really spoiling those games or leaving someone confused without having played them.

As this is a positive review I will start of with the negative points I can think off first.

• This is very subjective, but in my opinion the story only really gets great several chapters (or cantos) into the game. That is not to say the early chapters are bad, but I was only hooked dozens of hours into this game.
  
• The tutorial is very lacking and you'll likely need to read some guides or watch videos to fully understand the gameplay. The way the tutorial teaches combat, it overemphasises for example skill chaining, while there are a lot more important things to consider that fall short in the tutorials.
  
• Eventually the game will require you to grind side content to level up your characters to keep up with story content. The further you progress, the longer the grind will be. This is with the side content of "thread and EXP excavations" being pretty boring and repetitive due to it's grindy nature.
  
• Expanding on this, since the game is a gacha after all, playing any levels or grinding anything will require energy which will slowly restore over time. This is not too bad expect for grinding.
  
• There are various events that happen that aren't very accessible to new players. If you start playing you'll likely miss out on those that happen just as you're getting into the game.

• Despite the game being a gacha, those gacha core elements are by far not too excruciating. You can play the entire game without spending a single buck on it. You can even unlock almost of the "FOMO" (Fear of Missing Out) content every time without spending real money on it.
  
• As mentioned previously the story is amazing so far, even if the journey is not yet complete as of writing this review.
  
• The way the game treats its world building and lore is done very well. There are plenty of details that are mentioned in a matter of fact way with just simple comment and no further explanation. The details of the world of Limbus Company aren't shoved down your throat.
  
• The gameplay keeps becoming more engaging and tactical as you progress through the game and as more is being written and developed.
  
• Besides the main story, various events happen every few weeks or months. They too can be completed without spending any real money on the game, even if that means having to save up some in-game currency prior to such an event.
  
• The art style is great. The backdrops of cutscenes / dialogues and loading screens look amazing. And the in-combat sprites remind me of the Darkest Dungeon art style.
  
• The musical score of the game is great. There are countless of bosses in the game with amazing OST and even in regular battles there are countless of great tracks. Even bosses solely made for the late game game-mode "Refraction Railways" have some of the best themes.
  
• Lastly the voice acting is phenomenal as well. And ties it all together with the well written dialogues and musical setting.
