Well at least the vehicles look like they are from the same universe. The same can hardly be said for PT. The location rehash is a fair point, but in time they will hold up much better than PT worlds. The use of bad CGI to create new worlds resulted in effects that looked dated the year after the release and a few years after that pretty much anybody could replicate such effects on a personal computer. On the other hand, lot of the OOT practical effects still looked impressive decades after the release.

Also, art design would include costumes, the general aesthetics etc.
