One thing that will save a lot of bacta vials in this game is to look for a gunbelt that gives health for each adrenaline kill. They also tend to be instant heal rather than heal over time like the vials. I tend to prefer those over all the other gunbelt perks. 4xb calculation units are used for ship upgrades. There's a lot of space content that can be quite fun and a lot of upgrades supplies found in orbit. Late in the game you'll be in one of those epic Star Wars space battles, so all the upgrades you can get will be helpful. There's also a number of expert skills to unlock for ship handling like rolls, quick turns, loops, etc. Since you asked about it, the abandoned Lars farm where Luke grew up is one of the locations you can visit. There's also Toshi Station where he was going to go pick up some power converters before uncle Owen stuck him with those new droids. Docking Bay 94 in Mos Eisley is where you first saw the Millenium Falcon and Chalmuns Cantina is the place from the movie. Listen carefully and you'll even hear a customer talking about a cursed booth where people die a lot. It's kind of nice to see someone play strategicly like you did for the krait dragon pearl. Just take out who you need to and leave the rest. You don't often see that.
