Mos Eisley Cantina had a pretty decent mix of aliens.
Tattooine was described as being a planet inhabited mostly by humans and the planet's natives (in small populations) anyway.
Yeah, to me Mos Eisley in ANH felt much more like how a small, dusty little spaceport in the middle of nowhere would really be like.
There was something so much more compelling and evocative
about those sparse planets in the OT, compared to how ridiculously busy and overcrowded everything was in the prequels.
Hopefully that's another thing Abrams will try to get back to in his movies.
