Quoted from TheFamilyArcade:
I’m going to be putting some quality time on a route SW this weekend. Probably a pro, but not sure. Can anyone recommend a (fairly) simple approach to the game to have the most fun, get the most out of it and - to a lesser degree - score the best?
I agree with the assessment above to go with R2, especially if you're looking to work that multiplier for big points.
That said, to switch it up, if you want to get to Lightsaber Dual quickly to fight Darth Vader, choose Luke, then work on completing those FORCE targets. Luke awards you FORCE letters easier than other characters, so you should be able to get to the dual by at the very worse, your last ball. Then enjoy the LCD and light choreography as you step in the shoes of Obi-Wan to attempt to delay Darth Vader so Luke, Leia, and Han can escape to the Millenium Falcon. While not too difficult, it's a well put-together sequence.
