IF there is a KOTOR3 then i would recomend a few changes to that story
1) The exile either kills himself or retreats to the unknown regions in self proclaimed exile, and we dont see him until the final battle which includes a massive assault of a unknown race the exile recruited with ships in half oval design. also Revan sends a message through the force repeatedly to Carth and Batstila through out the game, but if ur ls, the shroud of the DS made it difficult to hear except to the new character you play for a period that switches b/w u and Revan. thus Bastila and carth must make a choice to defend the worlds the republic has left, or attack the Sith when they dont expect it.
2) a character you play for a time, switching with Revan and other party members.- preferably a team of jedi who were in hiding. Also the new pc should be able to be of multiple races, hell even huttese, force speed would be awesome w/ that. move at the speed of a catipillar...
3) fixed randomizer, with merchants who have half random and half GOOD important items that arent wastes of time to buy.
4) Lightsaber hilts and designs, tattoos, haircuts-if human or....wookie i guess
5) New movement for every lightsaber style, like juyo actually has the whirling and you get a force fury esque blur on the screen and the more xp ur character has in it, the longer u can last using it, it should be like that for them all so u dont get too powerful again.
6) good robes.
7) exile and revan both die at the end by sacrificing themself-ls for the republic and blow up the sith fleet or somethin. if ds then they use battle meditatioin to take control of the sith fleets and attack the republic at the end. using the exile to absorb the force as mass people die to keep the meditation going.
double bladed lightsabers like darth mauls that if u want can only have one lit or take them apart durin combat and use single blades. but u must have a VERY high repair and probly jedi mechanic feats or somethin where force items can be created manually and whatnot.
