[Star Wars] After the death of their mother, Luke is raised on Alderaan by Bail Organa and his wife while Leia grows up on the Lars Moisture Farm on Tattooine. How different are the events of Episodes IV-VII?

They don't change much in terms of overall effect on the Galaxy. Leia has the same force potential as Luke, and being cooped up on Tattooine would make her want to escape like Luke did.

The biggest difference would be Leia and Han would probably never become romantically attached. Without the affluent upbringing of Alderaan she'd have never needed the "scoundrel".

The biggest effect would be what the effects of upbringing would have on the temperament of the twins. Leia has the temperament of their father, where Luke is more similar to their mother. But Leia's in your face attitude likely stems from the stress of growing up knee deep in the rebellion which Luke would probably have inherited too.

So ultimately there wouldn't be much of a difference besides the actual context of events on Cloud City.
