>>9038584I might be misremembering, but I thought the "no wheels, no paper" thing was mostly Bob Thompson's doing, since he liked to throw random weird ideas into the story for fun, whether they made sense or not. He came up with Kapura walking slow to go fast too. After he left Lego, the rest of the writers were stuck with Bob's leftover ideas that they struggled to implement in the story. Greg was infamously unfamiliar with MNOG, so he probably thought the "no wheels" rule was still a thing and kept referencing it in his writings even if it would have made more sense to ignore it. Then the set designers came up with the Destral cycle and it all had to be thrown out the window.
The "no paper" rule was also a carryover from the early years. In a 2007 book the Nuva are weirded out by a parchment scroll with notes written on it, because they thought people only write on stone tablets. But the movies and the online games already established that Matoran use weaved fabric, plant leaves and foil to write on, so why would they find the notion of writing on something other than rocks so weird? Because Greg didn't think the scene through, he just remembered that Bob said paper doesn't exist and he stuck to that idea even when it made no sense for the universe anymore. Or perhaps the Nuva were also retards.
