I totally agree. As a 22 year fan, I’d love a little consideration thrown my way, but at the end of the day it’s the new generation of kids that is best suited to move this forward, as you say. I’d just be grateful for the invite, and I think that’s the attitude us old-timers should bring to the table. No accusations here, just a general viewpoint.
I would also add that I think, if they did do G3, they should make some of them, well… girly. And even more so, a bit less gender specific. Not that anyone was ever really barred from Bionicle, but the equation “Robot + Fight = Boys” was certainly prevalent back then, and Lego Friends has proven that this medium can lend itself to a broader audience. I think Bionicle can do that too, and it would be good of Lego to more actively invite other demographics. Might even be good for them, not bottlenecking the IP through a gradually fading stereotype. The social climate has changed, after all.
