I've always heard about it, but I don't know what to make of it.
I never fully knew what the contest was like, what media it was based on, or who the winners in the past were. I don't even know the rules or if there's an annual theme to the entries.
And as a Bionicle fan, while I've tinkered with the parts many times, I've made very few MOCs and often feel discouraged from sharing even among the fandom.
If I can find out where to see Bio-Cup, I can watch. I don't feel confident in my abilities and time to build for it this year however.
