But I'm also at that age when I look at things like this and think "neat", and then follow it up with "where the heck would I put that after I built it?" I simply don't have the free surface space.
I was given a Lego Star Destroyer as a gift. I built it, then gave it away for that reason. Now I have kids and wish I had it back. just for the pieces.
That star destroyer had awesome pieces. I used them to create all sorts of neat buildings and sets before I... gave it all away due to lack of space.
But life's revenge is sweet: now my kids have their own Lego spilling off shelves and out from under the bed in their rooms. And they're pragmatic enough to supplement with off-brand bricks and 3D printed bricks where the Lego sets are too costly.
