Before this, the only thing I knew about the development of the Toei anime was that Kakudou had also been called to work on the movie that was a part of the Toei Anime Fair, but he declined because he had already started working on the Digimon Adventure TV series.

I always found the "Digital Card Battle x Digital Card Arena" situation strange. I understand how long ago in Final Fantasy the Western numbering changed due to unreleased titles. But this isn't "Digimon Card 1 and 2", so why did they give the sequel the previous game's name?

In Digimon World, Jijimon asked the player if they had a Digital Monster. In the English version, released after the anime, they changed it to a Digivice. Funny enough, in Digital Card Battle, the protagonist actually gets a Digivice, said to be proof of the legendary hero.

"I couldn't go by the name Rosemon in that Matrix" "It might seem foolish, but as a Lady, I do have something you would call pride" I find it curious that although Babamon's profile is open enough that most interpret that Rosemon's body became Babamon, that wasn't the case.

I find Card Battle's Babamon intro very funny when compared with Digimon World. "This is a world where Digimon fight with cards. No need to overthink; it's just a strange, strange world." "You'll inhabit this young boy's body; it doesn't matter if you are an old man or a girl".

I remember watching Digimon World gameplay when I was young and always finding the inside of Mugen Mountain, a bizarre space of terrain wireframe, interesting. I like that Card Battle actually explored a bit of what that place really was; the Digital World's System Area.
