Is it a surprise that literally half of the stories on this list feature Balthier? No, it is not. I suppose it surprises me a little that the list is so FFXII-heavy -- only one X-2 story, and two FFX. Then again, there almost twice as many FFXII stories currently in the archive than there are FFX and X-2 stories combined, which suggests a higher readership for that fandom. So maybe it does make a certain amount of sense.
