The current reviews for this game are mixed at the moment of writing this and i wanted to throw my viewpoint into the mix.
Note that i used to own this on the PS4 but much like the few number of players, I got frustrated and decided to sell it on, didn't even get past the first chapter, few years later i decided to give it another chance after watching some streamers play it and getting some info under my belt.

This review was made after clearing Chapter 1 of the game. Many people might of picked this up because of their previous title "Digimon Story: Cyber Sleuth" but this is based of their "World" series of games, so its a whole different game. You are focused on raising up two Digimon from young and weak monsters, to strong and brutal beasts, however you are to manage their lifestyle, from training, feeding, even other toiletry duties. This game is meant to be played over multiple days as power does not come in a single day, because the game does focus on life and death also, your Digimon partners only have a certain life period before they move on, so do not get attached to them, however, as stated even at the beginning of the game, they are reborn, albeit small and weak, but they will have more upgraded stats depending on the egg you choose. Battles ingame are mostly self-done by the Digimon themselfs but you can cheer them on and give them some orders to try improve your chances of winning, and now a keypoint that people raise up, how its meant to be a "beat in one hit or lose", as while the enemy Digimon can be able to finish you in a single move, after raising your level, you can invest in a "Defend" command, which will mitigate heavily the damage you would take, improving your chances. Basically if you put in the time and effort, even the toughest of fights will be straightforward if you just keep an eye on the enemy Digimons movement.
Eventually you'll unlock more home-city features which will make your adventures more easier for future adventures, so while you could fail first time, keep on trying and you'll eventually make progress.

TLDR: Game is meant to take a while, life and death ingame will happen, invest in a Defend command, most fights will play themselfs, always use your items, keep on trying.

It's a game using the face of digimon as a means to sell itself, the gameplay is rough and everything feels unpolished, under no circumstances should you buy this at full price. If you love digimon enough, it's probably not terrible.
