As much as I would absolutely love to see more official material, I think the best way to go is making our own stories. Bionicle was what got me interested in writing in the first place, and for me personally it would be a disservice to waste that waiting around for Lego.
And I get it, a lot of fan projects have a pretty bad track record for producing results, and there's a whole other discussion to be had about that, but it's easy to forget that there have been successful ones as well; Reviving Bionicle, Struggle In The Drifts, and the upcoming Legend Of Mata Nui revamp release.
So yeah, I urge anyone who (like me) is hoping to see G3 or something along those lines happen someday, to start by making your own!
