I started building simple small (fitting for my then still tiny hands

) TOS communicators and phasers when I was 5 or 6.
In fact, when building something from Star Trek later, it was always something 1:1 like phasers, tricorders, communicators and so on. I still have a PADD made of Lego and a TOS Communicator.
What I can remember is a TNG Phaser (first version), TNG Tricorder, ST V+VI phaser pistol with detachable magazine, TOS Phaser pistol with detachable Hand Phaser and the TNG PADD.
Does anyone here know Startours? The Star Wars ride in Disneyland? I made a Starspeeder 3000 of Lego, fitting to the other Star Wars Lego stuff.
I think Lego was always good for childrens creativity. However, it has changed too much in my opinion. To many special parts, too few creativity. It hasn't much to do with what I used to know.
