Ok, here we go again, argue with the most all-knowing of star wars ever...
1- Well, Revan was a jedi knight, who became a Dark Lord of the Sith, Darth Revan, what to me means that he is a master of the dark side and it is stated that he's one of the most powerfull sith etc. After that he goes to the light side again and became a jedi MASTER (it is stated in the novel), which again, to me, means that he is a master of the light side. So, yes he mastered both sides of the force.
About the lightsaber fighting, it is stated that he was one of the best dualist of his time, wich was a time with a LOT of fighter both from dark and light sides and mandalorians, etc. So, even that we can't confirm that he mastered any lightsaber style, he probably did, and if he didn't, there is no difference, because he's still one of the bests.
2- He was a tactical genius as stated before, praised for a lot of fighters including mandalorians that are all about war. Just because you don't think he is and have no arguments to base this doesn't means he wasn't. You must remember that we don't know the majority of things made by Revan, actually, we know almost nothing about him and there could be situations that aren't shown to players that only canderous have seen.
3- Yes, he used both sides of the force. In the same time? No, not in the same instant but he could, for example, heal his wounds with force heal (light side) and after that kill someone with force lightning or force storm (dark side). This is use both sides of the force.
Also, he isn't the only one to do that. Kyle Katarn could do that too and so luke skywalker. Although they didn't like to use dark side powers fearing to fall to dark side.
Oh, and **** G-canon, **** what George Lucas says, he doesn't even cares for what he says and the repercussion that it would have.
This is so true. The novel and the game screwed with Revan character.
^^ Well said (with the exception of what you said about G-canon).
I'd like to talk about the whole "mastery" thing though. Did he master the force? No. But who has mastered the force? Not many. Revan displayed a great understanding of the force by becoming a powerful user of both sides (at different times). It's obvious that Revan had a great understanding of the force. Didn't Darth Bane himself say that Revan was a very powerful being?
Also - would someone explain to me why the following quote from Kreia ISN'T reliable?
"Looking at Revan was like looking into the heart of the force."
- yes, Kreia lies a lot, but there isn't a good reason for her to lie on this subject. She doesn't lie aimlessly. There's always a purpose, and I can't see the point in lying in this since.
- could she have been stretching the truth here? Possibly. Revan was her apprentice so she must have had great pride in him. But all this means is that she was exadurating a bit. So perhaps looking at Revan wasn't like "looking into the heart of the force", but he still must have been something for Kreia to say such a thing.
I honestly don't know why you guys refuse to believe that Canderous's and Mandalore's praise means nothing. I can't recall the exact quote in KOTOR #1, but I know that Canderous says something about swift counter-attacks and mass deceptions (there's a lot more). Who does Canderous say is responsible for this stuff? Revan. Not Surik, not Karath, and not Alek. Revan. Seriously, you guys have played the game. You'll remember that Ordo PRAISES Revan. No just a compliment, a PRAISE. This is coming from a guys who studied war his whole life. So please for pete's sake admit that Revan was a skilled tactician.
