I would like to see....
*Open Multi-classing, I want to choose each level which class to advance in or a new class to take.
*Optional NPCs, I want to choose which ones come with (example: Atton would have never made it off Peragus, I never had a use for him except as a plot train character).
*More NPC Interaction. I liked it when the NPCs would interact with each other while traveling with me (more like KOTOR I than KOTOR 2)
*NPCs who take you on side quests to planets that have nothing to do with the main plot line.
*More places to visit in the galaxy that have nothing to do with the main plot line (see above, also think Yavin station form KOTOR I)
*I would like to see the point buy system increased to at least 32
*Implants put back to feat/class feature like in KOTOR I and not based on Con.
*Keep no level cap like KOTOR 2 (I had more than enough XP to be 23rd level when I completed KOTOR I)
*A complete manual for the game, if not printed then at least as a pdf (I really hated skill points per level listed as fast, average, and slow....give me numbers!)
*Increase skill points/ level for each class (I think guardian should have been 2, Consular 4 and Sentinel 6 or guardian 1, consular 2, and sentinel 4.
* Keep the combat system the way it is, I found it easy and enjoyable.
* Modable, so new adventures can be created (I've never been one to play through games more than once, since the plot line never really changes no matter how you play it.
All of my thoughts on this matter that I can recall right now
