Different demographics that can coexist. The fact the Uni still has more events, tamaverse tickets and even a corner shop integration suggests that the Paradise is not a successor but a separate product category.

Plus = JINCO evergreen art style
Paradise = "trendy" art style, something new, what happens long term might determine on its success
