So this was originally going to be a topic restricted to Bionicle, but I figured there's plenty more to be told about other Lego themes as well. Post an interesting story about your collection! Whether it's getting your first set, first encounters with a theme, the story of growing your collection one day, the order in which you obtained certain sets, just another something to share out about your collection!
I have a small story to start, regarding my Bionicle collection. So, being a fan that entered the game a few years after the initial release of Bionicle, I jumped in barely knowing anything about 2001 (I joined in about 02-03). The only thing I knew (or thought) was that the Toa Mata were something of a rare treasure that had to be had (I was young). The lore and 'mystery of what this 01 was about' was so intriguing to me, and there's just something about old Lego sets that interest me. I had no idea how, but come Christmas 2005, I believe, and I got all six Toa Mata, complete with canisters and instructions! Ta-da!
