Just out of curiosity, which Bionicle sets were your first in these categories:
First sets (general)
First Average Set (like regular Toa sized [Unless already said])
First Small Set (Matoran, Agori, etc.)
First Favorite (Not first set by default)
First Least Favorite/Disappointment (Not first set by default)
First Vehicle set (If any)
My first set was Kalmah, my first titan was Gadunkah, my first small set was Gavla, my first favorite was Matoro, my first least favorite was Onua Mistika, and my first vehicle set was Toa Ignika.
