So what are some Lego related things you want to do someday?
Here's my list:
Build a G1 Devastator.
Build a Rotf Devastator.
Paint a kanohi.
Buy multiple of a large set (Example: 10 Star Destroyers) and get as close as I can to a properly scaled version of that set with just those pieces.
Make a mold of a kanohi and melt down a (or how many are required) kanoka into it to IRL forge a mask of power!
