I would like to see more romance in these games. And also, I would like a bunch of different planets to go to, instead of having different branches of the same planet to go to. Planets I would like to see are Coruscant, Mon Calamar, Ithor, Duro, Alderran, Bothuwi(sp?), Ryloth, and Chandrila.
I also would like to see a different ship other than the Ebon Hawk. I would like to either have some old characters as party members, or would like them to make cameos. (Particularly Atton or Mira, b/c they were cool) I would like to see more faces to choose from when creating a character. And I would like to have multiple bosses like in KOTOR 2, with the Sith lords. And I would like more backstory for the companions, and I would like to see more human/alien companions than droids. Truthfully, I rarely even used the droids. Except for T3-M4. He's a pretty handy little droid. Especially on GOTO's Yacht.
I also think it would be interesting if the main character were a regular person unaware of their force powers, not one who was already a Jedi like Revan.
Or the main character would already be a dark Jedi, and they could either turn to the light side or stay dark side.
Or the main character could be a criminal, and the Jedi would have to break them out b/c they are key to saving the republic.
Anyway, these are just some of my ideas.
