More Infinite Experience
Here's a way to score infinite experience points. Head to Dantooine and enter the Kinrath Nest. Defeat Kinrath and its hatchlings, but don't advance to find Master Vrook. Instead, press start and switch characters, and then begin to walk back towards the entrance. When you do this, hatchlings will materialize and attack. Kill them, and then repeat the process over and over again for infinite experience.
