I didn't realize you couldn't reuse the Legos from the specialized kits. I better go tell my kids who have built all kinds of crazy contraptions over the years. Frankly, I think having a bin full of parts that used to be a few different kits makes for a lot more creativity than having a bin full of standard Legos. There are so many more options.

Repurposing special kit parts for your own builds is one of the best parts of Legos.

It's an early age manifestation of the hacker ethos - taking some thing and finding all the ways you can use it outside of its original intent, and then putting those disparate things together to build something entirely new.
