I'd like to see some Exo-force sets in Lego's new quality.
I had most of the old Exo-force sets, and they were awful. Brittle things that came apart if you touched them wrong.
However, I've had a few mechs since then (Nya's samurai mech comes to mind) and they were much better.
Also, the animations and comics were pretty good (nay, great), although the books left something to be desired. Y'know how G1 BIONICELL had the main story fleshed out in the books and summarized in the comics? Yeah, Exo-Force was the other way around.
Yes, I just said Bionicell.
It was not a typo.
