I have been getting some questions and I realized an update is in order. At this point in time construction on Jama has been halted. I intend to use the money and effort to goto Bricks West 2003 in California rather than spend it on Jama. So at this (...)

Yes, to my amazement, both the Manas and Spybotics were packaged in this manner (in the U.S. at least). I can't fathom what on Earth they were thinking when they came up with this packaging scheme. The controllers that came with the Manas were badly (...) (23 years ago, 27-Dec-02, to lugnet.robotics.spybotics, lugnet.lego)

Merry Xmas! We just unpacked a spybotic and some other LEGO. I am really upset about the way LEGO is packaging new stuff. We have a box here, with loose content, just filling 1/3 of the box.
