Lmao, Lightsnake.
a)
You did notice that Mr Chee didn't even notice a contradiction in the source material ? Read this here:

And Mr Chee's reaction to this seems to be ignorance. Maybe he noticed that they did cause some huge mess with the NEC at this point ?
b)
You should read your own arguments.
Games and RPG sourcebooks are a special case; the stories and general background information are themselves fully C-canon, but the other elements such as character/item statistics and gameplay are, with few exceptions, N-canon.
Games and sourcebooks are a special case. You have to consider the overall ranking in terms of C-Canon:
Books > Comics / Cartoons > Sourcebooks > Games
The sourcebooks aren't able to overwrite statements given in the Comics or Books since they are just additional information on certain topics. POTJ sourcebook labels Yoda the most powerful Jedi (even compared to NJO Luke). That is dumb. And the statements about Sidious aren't canon either. Live with it.
c)
The two comics released dealing with the Ancient Sith Empire (GAotS, FotSE) were released in 1997 / 1998. Empire's End was released in 1997 too. Same with the DS sourcebook.
d)
Dan Wallace can toss in his opinion like he wants but an inconvenient fact for you: He isn't able to contradict Anderson and Veitch who invented all persons (DE Sidious, the Ancient Sith Lords) who labelled Ragnos the "most powerful". And his statement that Sidious was the "greatest" doesn't mean "most powerful".
Yeah, yean, IKC, isn't it great this isn't a sourcebook? And Scourge's contradiction was fixed on the boards: The sith species extends back millenia, but the empire was established 7000 BBY. See, it's really simple. It was retconned and LFL accepted it. Leland Chee confirmed it, YOU HAVE NO ARGUMENT.
And since the NEC contradicts nothing, has not been retconned and is a BOOK, it goes. And Nai, did you not read what I posted? Sidious is declared the most powerful, plain and simple. I scanned in the damn page
Which is why sourcebooks have overwritten books and comics before, right?
