BlaneckW: No, that's literally what it is, you're running along the linear quest line and there's this guy preaching let's burn down the alien ghetto.
That's one minor character who has literally nothing to do with the overall plot and story. He's just there to annoy you (or not, if you lean towards the "burn 'em all" philosophy)
The decisions in this game do basically boil down to "be a jerk, or don't be a jerk, your choice", but that is what passed for a moral decision dilemma in RPG games back in 2003. Its a formula that BioWare did refine somewhat in later games like Mass Effect. Obsidian actually did a better job with the KotOR sequel, some of the decisions weren't quite so black and white, they had shades of grey.
As for your level, well, I hate to say it, but you screwed up. While you can level up to pretty much the max before you become a Jedi, you aren't supposed to. You can actually level up to around 2 or 3, then just stop leveling until you become a Jedi. You continue to accrue experience, you just don't "spend" that experience until you have Jedi powers to spend it on. Since enemies level with you, the difficulty never even goes out of whack. Eventually you will easily hit the level cap (20 was way too low) and will probably spend at least the last third of the game maxed out, but because of the leveling you already did, you ended up a level 12 soldier (or whatever class you chose) who is also a level 8 Jedi, not much more than a Padawan. Had you reserved some of that leveling, you could be a basic soldier who is also a freakin' Jedi master.
As for the attraction, its Star Wars. Everybody loves Star Wars. Better, its Star Wars completely unencumbered by the lore of the movies. And you get to be a bad ass Jedi (or Sith, whatever floats your boat). Nothing like it had ever existed in gaming before and unless certain attitudes at Disney and EA change, is unlikely to ever exist again.
