Thanks for chiming in.
The thing is, you can't mix and match LEGO kits. zzz
Have you really play with LEGO kits? You can only build 1 thing. You can put things "together" side by side... But that doesn't mean you "create new things" out of nowhere. You literally just put whatever the kits provide you.
For example: You can have LEGO kits of flower and castle. You put them together FLOWER + CASTLE. But that's it.
Thus, the analogy.
