One of the biggest cases of "perhaps I treated you too harshly" I had in vidya. Once I had spent most of the time just clicking through automated gymming the game was horribly boring but once I learned actual exploration and fighting enemies reaped more gains the game became good. UI a bit clunky. There's an exhilarating complexity here and you have a very precise moment in your digimon's finite life where you're strong so you have to really haul ass. Expanding file city is richly rewarding

Took almost everything I liked about the first one and made it better. Some things I like less are the fishing (you could make an argument that this wastes less time) and how much walking you have to do to get around. Almost everything else is improved, the same, or different but still good.
