Yeah, seems like there’s tons of material they could use. Maybe even start the player as 8-bit Mario, levelling up to current Mario standards/graphics. The playfield/toys could be a veritable “world under glass” with subways like the green tubes, warping players through worlds. Would love to see a toy like a giant plant, for example.
Would really need a high b.o.m. On a solid Mario game to do it justice!
