It’s literally taken until this year for the wall of jackets to be recreated in StepMania without major issues (I personally consider the bottom row overlapping the folder like it does to be a major issue). When you scroll you can watch the jackets “shift” so to speak on folders where the bottom row overlaps. It’s very hacked together. I think it was around when Starlight 2.0 was released that the same issue for the top row was fixed. It’s taken years and a lot of very talented people to figure out how to make this kind of song wheel in StepMania. Konami has the advantage that their game is made to do it in the first place while StepMania is not made to do it at all which is why I referred to it as hacked together.
But generally I agree that World looks like a StepMania theme. Especially with how bare bones and empty it was at the beginning, combined with the speed mod options, it reminded me of DDR’s version of Simply Love. It wasn’t necessarily bad, as a matter of fact I liked it, but it definitely didn’t have the visual flare that screams “this is an official DDR product”. It has a lot more to it now and looks really good though.
