I wanted to make this post so other people can compare their games with mine. I'll try and be as detailed, yet brief about all the things I did in the game.
Male light side consular/Jedi master. SPOILERS, obviously.
Kreia - I gained enough influence that Kreia revealed everything. Knowing Atris, knowing Revan, knowing the Sith that pursues me, knowing Visas' master, revealing her own exile/fall. I assume the following are suppose to be revealed, to show her role in the entire game. She discovers Atton's secret on Telo Academy, she talks with Mandalore on Dxun right before the shuttle trip to Onderon, she tells me not to get involved with Visas and Handmaiden, she enslaves Hanharr, she gets Colonel Tobin to go to Telos, she kills the Council on Dantooine once it was reformed, she reveals her secrets to Atris, driving Atris over the edge. I think that's it...
Atton - I discover his secrets, with him killing the Jedi and how she protected his Force sensitivity to the Sith, he offers to become a Jedi, but I turn him down (in this game, I don't actually do the final act to make them a Jedi on purpose). He tells Kreia that my character knows, so she has no power over him anymore. She then threatens to unlock his dark side so that he enjoys killing and such again. He and the Handmaiden goes at it about the Echani forms, and how he knows she's being close to breaking protocal with me during the spars ("fool, schutta!" great exchange ^_^). I learn how to "count pazaaka" from him. He tells T3 that if he's yelling, he it's because he cares. Atton has the scenes with Kreia about my character and how main character can learn with without the Force and such.
T3 - I only repair him twice. He knocks out HK-47 when HK confronts him about the nav computer. Bao-Dur upgrades T3 once. I confront T3 about knowing Kreia was on the Ebon Hawk when it was attacked. T3 wouldn't talk, even when I actually THREATENED him.
Bao-Dur - I didn't even get close with turning him Jedi at all. Upgrades Goto twice. After Freedon Nadd's tomb mission (my party was myself, Kreia, and Visas. Dxun party was Mira leading, Mandalore, and Goto), I tried talking to him about Dxun, but he doesn't reveal anything.
Handmaiden - I defeat her 3 times, but I don't offer to make her Jedi. I do all the steps needed to make her Jedi, but don't actually do it. Also, because I don't even bring that subject up, Kreia doesn't send the Force message to Atris about betrayal. She warns of Visas when Visas joins of course, but no catfights (if there are suppose to be). I did not get enough influence with her to get her to talk about Atris. Handmaiden revealed she cared about my character (I thought I lost you) during after the fight with Atris.
Visas Marr - I only got the same dialogue options about "who is your master, who sent you, how did you find me, what happened to your homeworld, and did your group destroy Peragus". I took her on Korriban and got some minor dialogues about Korriban being powerful and darkside. I think it was right before getting back to Telos did she mention her master, then she talked about loving you, caring for you, wanting to know how/why the Handmaiden loves you, and then we "saw" each other in the Force. She felt better once Nilihus died. I encouraged her during the fight, and she begged her master to punish her for betrayal, and to let me go.
HK-47 - I didn't get anywhere with him. He had a conversation with Goto about how Goto thought HK-47 was destroyed, but he was wrong. I already mentioned that T3 owns HK during the nav computer talk. He interjects himself briefly when I asked Mira for lethal grenades. Mira got really annoyed with HK talking about death and killing all the time (funny).
Mira - I found out everything about Mira, and could have turn her into a Jedi, but didn't take her to the spot on Nar Shadda to trigger the change. I used her as the party leader on Dxun during the Freedon Nadd tomb. I made her slightly interested in the darkside. Afterwards, she didn't really want to talk about it, but did said she felt like she knows herself better now. She follows the main character on Malachor V, fight Hanharr, and I let him live yet again. On Onderon, when the bounty hunters attacked me, I told them to leave her alone, and gained influence.
Goto - I read the spoilers, so I know he's a droid, but in the game, I didn't bother doing it yet. He talked 2-3 times with Bao-Dur about upgrades and such. He destroyes Remote in the engine room in one cut scene. At the end of the game, Remote activites the engines, and then Goto shows up (no resolution on this at all, from what I've read). Never got any influnce with him, and he refuses to make me security tunnelers, even when I was actually out.
Mandalore - Don't recall anything specific happening with him. I got him last however, so probably missed a lot of things with him.
