Rules question spending xp

By A disturbance in the force, in Star Wars: Edge of the Empire RPG

Dude, seriously, NPCs built with the same rules as PCs suck. I can't think of any recent system that builds enemies according to PC rules. D&D 3rd edition kinda did, and the result was long stat blocks with a bunch of horsecrap they weren't going to use. Orc #3's job is to swing his axe two or three times and then die. Troll Chieftain's job is to be big, get hit a lot, and then die. He doesn't need five ranks in Craft: Pottery to do that. D&D 4, D&D 5, Savage Worlds, The One Ring, 13th Age, Legend of the Five Rings; these are all games where you grab a bad guy, tweak him as needed to make him a challenge, and turn him loose. Many of them explicitly say, "do not build NPCs as you would PCs."

If I'm playing Anakin Skywalker as a PC, leveling him all the way through the prequels, and playing his (melo)dramatic fall to the dark side, he's going to be a particular character. He's going to have several specializations, he's going to have weird talents here and there, and he's going to have ranks in unexpected skills, because back between Attack of the Clones and Revenge of the Sith, the campaign took a weird turn and he got really into Reggae. Did you know Darth Vader can make a bong out of a Tusken skull and that the little red button on his chestplate plays Redemption Song if you push it? No, you don't, because his three ranks in Knowledge: Stoner Lore don't help him kick a PC's ass.

If I'm running the game, I'm not using Anakin the PC. Darth Vader the big bad NPC has the stats and talents needed to deliver a beatdown. He doesn't have Dodge, or Side Step, or the defensive Sense upgrade. He has Adversary. "What's powering all those upgrades to hit him?" Badassery, that's what. The smooth, deliberate voice of James Earl Jones, that's what. He doesn't need all those tech talents that let him build droids and modify his starfighter. The droids are built. He has them. His ship is tricked out, it has cool stats. We're not going to worry how he modified it, or how much it cost to build that ship. It's there, it's behind you, and it just blasted a hole in your ship.
