The reason I like the "Without Magic" is because of the sidestories. Of course I love the main story about Twilight(as you can guess it from my profile pic), but I really liked the Trixie sidestory part.
Might sound stupid, but it affected my Trixie headcanon, like Pony Fantasy VI did.
So anyway what I just wanted to say is that I liked your series, especially the Trixie side story part. Really.
