Quote from Saandro »Tldr of Kamigawa: ''It has a high rank because it wasn't popular (citation needed) and didn't sell too well. We might revisit it if we discard everything good about it and go with animes and ninjas because they are what's popular and marketable these days.''
I hate how Maro is such a biased salesman behind his rational facade. For example the new worlds all rank rather low with very questionable reasoning on some of them. Can't wait for 2025, when he will be able to talk about why Amonkhet or Ixalan failed and how the new return to Ixalan will totally fix all that and be super special awesome!
First of, and I will fight for that, Amonkhet was awesome. Being a small plane with a single self-contained culture is not always the bad thing some of you are trying to portray it as. In this case it was even justified, since the plane is described as being nearly dead and having suffered from a catastrophe way before Bolas got his hands on it. There just isn't much left of it. (I'm actually mad about Maro seemingly thinking that it blew up at the end. I mean, there were survivors and Hazoreth still lives as well...) I would also argue that worlds with actual gods which interact more or less directly with the populace would pretty much force the cultures on these planes to be relatively homogenous, so I don't see the problem with Theros and Amonkhet not having the varied cultures of Tarkir or Dominaria. Ixalans problems were mostly about the moral superficiality, NOT the actual worldbuilding, which was in my opinion pretty well done. Not my favorite world, but still.
Now Kamigawa. I personally liked it. But from what I can gather, many of the Kamigawa fans here seriously try to downplay how much even the flavor and worldbuilding was rejected when it came out. You might lament the fact that taking out the spirits etc. and introducing more popular japanese tropes into it is making it more superficial, but remember, tropes are not bad. In fact quite a few things in Kamigawa were so far away from the actual japanese mythology that the connection felt kind of forced (I don't really see much of a connection between the kitsune in the legends and those on the plane for example, except for that they resemble foxes). And let's face it, many parts of Kamigawa simply failed. I'm not even agreeing with it having "varied cultures", since everything is very clear cut between color lines in that regard. That's the thing I personally liked the least about it: It felt small and very much divided into cultural units. You had humans from each color, one nonhuman species for each color, one location for each color. Not the most creative way of worldbuilding. So I get Maro. Still, I think a compromise could be made to "modernize" Kamigawa without losing too much of its identity and that this would be worth exploring at least in a supplemental set.
