Well, just remember that “close” is quite relative when dealing with a map that covers an entire galaxy.
Yeah, I get that. It is just further shrinks the Star Wars galaxy. I understand the need to have Scarif near Tatooine in order for the events of ANH to kick off.
In AOTC, Obi-Wan’s long range transmitter is damaged and so he can’t contact Coruscant directly. Instead he reaches out to Anakin on Naboo to retransmit his message for him. Except, Anakin isn’t on Naboo but Tatooine. This places both systems within range of Geonosis.
