Hello there - I've started working to build up a FoA collection. After missing out on the promotion, I finally found a Jangutz Khan - also got a few Crystallites as well.
I only have one RAMM though (had two but one...kinda got knocked into an air vent as a kid), so looking for those (especially Rammpolis & Rammbler), as well as maybe Ironhaus's Dr. Dark
One idea of mine is to one day build some Dioramas inspired by the concept art to display FoA figures on. And maybe some fan art at some point.
