I actually loved the whole game, but the levels that had replay value (with a trainer so you can do whatever) for me are:
  1) The first level, just killing all those droids is kewl. 
 2) Mos Espa: KILL KILL KILL

 3) Garders: Droids

 4) Final Battle, against Maul: just a great mano-a-mano fight. Duel to the Death. No force push, no guns. Just lightsaber action.

 You can do it your own way
 Just as long as it's done just how I say...
