PROFILE

I would say Fabuland is also an early version of this and imo much better, simple boat,car and plane and buildings.

When it comes to that hidden price guide,Shouldn't it just track changes in price. ie if the price remain same don't do a entry, and limit the number of data points to 100 (3+ months worth of changes). That way all sets will have data in that field even if they are rare and barely sold. (as long as one set has bee sold since the feature started monitor the channels) That is the problem with bricklinks price guide data is flushed after 6 months, so if you find a rare sets you won't know what it's worth.
if a set is unavailable put it down to zero, so we can see not only value but availability. ie when did the last set sell and how long did it takes for it to sell at that price.

Why is this MOC using "any" color for the black parts, that color should be used for parts inside the MOC not for visible parts which should follow a color of the designers choice, ie "black" in this case.

No they are just ugly, so everyone doesn't love them that statement is so wrong. they are as unwanted as whatever the cat drags home. if it wasn't Lego variant because I can always use the parts to something else.

I do not understand why Lego keep putting out these electric kits/parts with a fixed cable. I so prefer the old times where the cable was it's own part and you could choose the length needed for your build. and if a cable broke, it was cheap to replace compare to replacing the whole engine/sensor which aren't broken. so I still think both the old 12V system and the first 9V versions is the parts you should use when building MOCS with electronics.
