After a drought of localized Digimon games, Digimon Story Cyber Sleuth was finally released in the West in February 2016. Digimon Story: Cyber Sleuth had almost everything an avid Digimon fan wanted in a new Digimon game -- similar battling to the beloved Nintendo DS titles, a decent amount of Digimon, and a world which felt like the near-perfect combination of the popular anime films Summer Wars and Digimon: The Movie.
There are a few glaring flaws, but how much they're noticed depends on the player's prior knowledge of the franchise. Some digivolution lines are intact, while others are all over the place and connect Digimon species who would otherwise be unrelated to each other. In addition to this, Digimon you haven’t seen or obtained will show up as "who’s that Pokémon" style silhouettes, so you'll have to find out what they are yourself or look up a guide.
It's not the worst since you can just dedigivolve them and level them up again if you you're unsatisfied -- an easy task when having experience boosting Digimon and items later on in the game, but a tedious activity in the earlier parts. The most irritating part of the messed up digivolution lines is that some Digimon which are not obtainable in the game (despite the rest of their line being obtainable) will still be seen on collectible medals. So it's a bit odd these missing Digimon were still put in the game that way.
Hopefully, the upcoming sequel, Digimon Story Cyber Sleuth: Hacker's Memory, adds plenty more digital monsters, and fixes these and other minor flaws from the original. But otherwise, Cyber Sleuth is another great alternative to Pokémon.
