What we've seen in Episode 13 of Ghost Game was mostly a consequence of what has been building up for the past 12 episodes, the writers behind the project were really smart to foreshadow and imply that the things in episode 13 would happen and everything is super coherent and fits really well.
On the other hand, we have Adventure 2020, Ad2020 is an example on how not to set a narrative, due to it being mostly a repetition of the same initial arc over and over again, the main issue is that the beginnings of Digimon series tend to be poor, and thats a constant that happens with all seasons, so if you decide to repeat the worst part of your series over and over, the final product will also be bad.
