I'm excited for both series and seeing where they lead me.
Tatooine I think holds a special place in Star Wars lore - the home of Luke Skywalker/Anakin Skywalker, and the most wretched hive of scum and villainy.
BoBF should expand to the rest of the Hutt controlled territories, but at least in episode 1, it looked like he was trying to gain control of just the one planet. The Hutts had more in the books, but on screen, they've never really left Tatooine, except for a few minor appearances in Clone Wars/Bad Batch.
I've often thought about the lack of bio-diversity in the Star Wars universe, not between planets, but on specific planets. Tatooine is ALL desert, Hoth is ALL ice, Coruscant is ALL city, Endor and Yavin are ALL jungle, Daogbah is ALL swamp. It makes it easy to distinguish worlds, but we know most planets have multiple bio-spheres.
Naboo is again an exception, given it has grasslands, cities, swamps, and a massive underwater eco-system.
