What are other significant examples of high attribute scores affecting your dialogue options? I'm not asking for all of them, obviously, but what are some other ones besides:

 

1) High intelligence to repair T3's memory core and seeing the message from Carth or Bastila

 

2) High intelligence or wisdom in the conversation with Kreia about the destruction of Visa's planet.

 

Any others worth mentioning?

I'll give it my best shot.

 

INT affects computer use, repair and adds skill points when you level up.

WIS affects force points, security skill and adds points to treat injury.

CHA affects your persuade checks.

 

I hope I was able to help a little.

As a general rule high awareness, computer, repair, intelligence and charisma are good for unlocking dialogue options.

With the droids intelligence and computer come into play most, while awareness and intelligence is for the "meatbags."

I've seen awareness options pop up for Kreia, Disciple and Visas.
