i disagree. it could actually be used to teach in some forms architectural design.
No.
3D modellers would be used for this since that is a valuable thing to learn for the industry. Why the hell would you use a kiddy lego game as a serious or budding architect? You wouldn't.
I dunno about architecture, but if you ever take a secondary school design course (furniture and basic spatial design) you'll quickly learn why something like Blockland would be inappropriate.
Events may be good for increasing logical thinking and perhaps a kiddies introduction to understanding programming, but ultimately, its entirely useless outside of Blockland.
There is absolutely no room for Blockland in education.
