*Agrees with above*
You have to back up your claims with unbiased facts.
You have to understand that people who go to forums and bother posting on a Star Wars one are mostly geeks. Now, geeks are the hardcore fans, not the average fan, known fact, undisputable. It is natural for them to know about EU and for a certain majority of them enjoying it. It would be like me going to a Republican convention and asking if they liked Bush.
I would also like you to post actual evidence of people wanting a Yuuzhan Vong civ in SWGB2 instead of just claims.
If you knew how to debate, throwing baseless claims never helps your credibility.
