And now to see if this can have mass cross-cultural appeal.
I have my sincere doubts.
The main issue by far is the level of context this game expects you to have in order to see the major appeal of it's charm. It is very heavily tied into Japanese folklore, iirc. While Pokemon of course had its Japanese cultural aspects, it also later drew on other cultures while simultaneously having its own world that it depended on mostly. Also, the character design for some of the creatures is a fair bit more bizarre than what other games bring. So I have my doubts, but we'll see.
