*SPOILERS*Why was Revan and so much in kotor retconned

A) Revan was drained of energy over 300 years. B) These aren't just four noodies. They're more like the champions of the Empire. Not just a run of the mill warrior, inquisitor, etc.

Does this Revanism know no end?

Fixed

Drain or not, we've been waiting since KoToR to see Revan again. It's a shame they brought him back just to get rid of him as quickly as possible. He was a very interesting character, with a unique perspective of the Force.

I hate what they did with the Exile. Where'd the ****** General chick go who took down Sion, Nihlus, and Traya? She's jealous of Bastilla? She retains unflinching faith in the Light Side after KoToR II? Did she learn nothing from Kreia?

And poor T3 and HK...

I have said this before and I'll say it again, they blew their load too early. All these years of build up, fleshing out the heroes and villains of the Old Republic, only to kill them all off in the release of a game that's supposed to last?

And don't get me started on Vitae...totally belittles Nihlus, Palpatine, and all other great Sith, canon-wise.

You got a funny way of spelling 'The Emperor's Wrath'.

Vitiate has nothing on Palpatine. Vitiate is still powerful but Palpatine did crazy stuff in EU.

I don't think we've see the last of Revan. No one in any fictional setting, especially Sci-fi/Fantasy, should be considered dead unless there is a body and even sometimes that doesn't guarantee death.

Except he doesn't. Palpatine is miles above any other Sith except Caedus. He summons planet-killing, fleet disintegrating wormholes that can transport people he chooses acrossed the Galaxy. He's got Galaxy-wide Battle Meditation. By Dark Empire he and Luke are engaged in a duel that occurs at speed that boggles even a Jedi's ability to perceive. Not to mention mindwiping all of Coruscant at once to forget about the Lusankya. Oh and Palpatine can do what Nihilus does, only he can actually control it.

As for Nihilus I honestly couldn't care about him being outperformed by a fifteen-hundred year old body jumping malevolent being, it says a lot about Nihilus that it takes that much effort to top him.

Lets look at the endings of KOTOR before they retconed it,

Dark Lord Reborn: Republic and Jedi are all but dead, Starforge is reaching new hieghts of infinate fleet, disidants can be thrown in those pods to keep Revan healthy and strong, and he has a companion who has a force power capable of turning the tide of battle.

All in all Revan is nearly unstopable and Sith Empire isn't a threat.

Revan Redemed: Republic and Jedi order are saved and have a new guardian to lead the republic and jedi into rebuilding and strengthening themselves before the sith arrive.

Not quite as great as an infinate fleet but the Republic would have been far stronger and unified and jedi now have a path to using both sides of the force.

How can they trivialize Darth Nihilus? He's dead.

Except they didn't.

First of all Revan understood that the Starforge drains the user and it was only a temporary use. Second we only ever see Force Users in those pods so it's not an infinite source. Third Battle Meditation was rare during the Jedi Civil War, not in later times. There's nothing here to suggest that the fight with the Reformed Sith Empire is going to be at all easy.

Jedi can't use 'both sides of the force'. This can't be laid out any more simply, 'Once you start down the dark path, forever will it dominate your destiny'. Revan didn't master the Dark Side and the Light Side simultaneously, it was always one or the other.
That's not how the Force works. You can't use 'both sides of the force'. This is quite explicit in RotJ when Yoda says it and it's further laid out by Luke in the Dark Nest Trilogy that there is a dark side and if you use it you WILL fall.
Apparently a Sith Lord stronger than Nihilus somehow makes Nihilus lesser.

The weirdest thing about that is that Darth Nihilus is described as weak by both Kreia and the Jedi Exile if she has a high enough wisdom score. The force hunger gave him power, but it came at a terrible cost. He was already dying when you fought him on Telos. And he would have died, even if he killed you.

you could play republic and save him

radical I know, but just think about it
