The prequels seem to have jettisoned this kind of feel. As good as the CGI is, the settings lacked the texture and the life that made these fantastical films feel real.
Yeah, whether it was intentional or not, the fact Lucas had to rely so much on real locations for the original movies did a LOT to make those worlds feel like real, tangible places.
Half of what made those movies so magical was the way you could easily imagine yourself with Luke under the searing heat of Tattoine, or trudging through the freezing snow of Hoth.
I never felt that with any of the new worlds in the prequels. They were so fantastical and overdesigned and overpopulated that I couldn't identify with any of it.
They still filmed in real locations.

Filming began on June 26, 1997 and ended on September 30 of that year, primarily taking place at Leavesden Film Studios in England, with additional location shooting in the Tunisian desert for the Tatooine scenes and the Italian Caserta Palace for the Theed City Naboo Palace interior. The city of Mos Espa was built in the desert outside Tozeur. On the night following the third day of shooting in Tozeur, an unexpected sandstorm destroyed many sets and props. With a quick rescheduling to allow for repairs, production was able to leave Tunisia on the exact day originally planned.
