I was a LEGO® kid. And now I am a LEGO® parent. As a kid my favorite was to build marble runs with the Legos I had back in the day. Now there are so many more parts to choose from. We have multiple LEGO® sets and bins upon bins of additional parts. We are working on the ultimate LEGO® Marble Run. But sometimes it helps to have a few specialty parts for curves, gentle slopes and smooth transitions.
