The best way to prepare for 'Star Wars: Obi-Wan Kenobi' is to watch this 4.5-hour Episode 3 supercut a few times

Exhaustive list of Star Wars properties worth watching or playing:

Episode IV A New Hope
Episode V The Empire Strikes Back
Star Wars: X-Wing
Star Wars: Tie Fighter
Star Wars: Battlefront (and maybe BFII)

I think that’s pretty much it.
