I had Digimon World 1 as a kid but I didn't understand how to play it 😂 and I somehow figured out how to play Digimon Card Battle, I can't understand how my brain worked back then.
Yeah the game is underrated, I never turned off the battle animation, I even downloaded the game on an emulator about four years ago, it's just as fun as I remember from my childhood.
Btw have you heard of Digimon Survive? If I could pick a single game that I want so badly that would be it, it's basically a mix of two of my favorite things, Devil Survivor and Digimon, unfortunately they haven't announced the release date yet.
