Sorry, I can't speak in Japanese so I'm replying in English. I hope I'm able to communicate with everyone.
For me, it's Digimon Story Cyber Sleuth and Hacker's Memory. I have been playing it since August 2021 and I love this game. The story, the characters, the digimon available to raise and train... I think this was one of the best gifts I got from a friend. I'm glad it was released for PC later, because I do not own a game console to play it. I have yet to finish Hacker's Memory though...
I also think Digimon Survive is a great game with a good storytelling and characters. I like the idea of having different endings in a game, but not more than 3 or 4. I liked how your actions defines your partner Agumon's evolution routes.
