I'm sure I've made a list of my collection of Bionicle sets somewhere earlier in this topic, but since I've apparently not updated since the reboot series (commonly referred to by fans as "G2"), I think I'll go ahead and make a complete list of my entire collection.
Actually, I'll just make a complete list of what I consider to be every Bionicle set ever released, and the ones I don't have will be underlined on this list...
