i wonder how lego set creators come up with new retail sets, using pieces that have never been in another set before.
do the guys at the lego factory come to them and are like
"hey guys, here are a dozen new bricks never before seen, and here is the theme we want you to follow, make us a set using these"
would seem way better if they were given a theme, and then openly allowed to help themselves to the huge allotment of available legos as they wish.
