| Well, as you surely know you become a Jedi at a point later in the game. Since the level cap is 20, and the experience jumps between levels gets bigger and bigger, some people like to "save levels" when they are not Jedi early in the game.
All it involves is not clicking the button to level up, like you say. Once you get to Dantooine, at some point you choose a Jedi class, and from that point onwards you level up in that class alone. At which point you use all the level-ups you've earned, so you are instantly a level 3+ Jedi, instead of just one. Of course it depends how many levels you save. You will be level 9 total once you select which Jedi class (should be anyway!). So if you didn't save levels you'll be 8 normal/1 Jedi, if you saved 4 levels you'll be 4 normal/5 Jedi, and if you stopped at 2, you'll already be a level 7 Jedi. Just gives you a head-start on the Jedi powers, which are by far the best ones in the game. With the bonus feats, ability to use a light-saber (which you should be using!), along with things associated with that - blaster bolt deflection, fully upgradable, by far the most powerful weapon in the game, and of course force powers. By saving levels you naturally end up with more "force-points", which is what you use up by using your powers, because you only start gaining them once you become a Jedi.  |
