Juniorization
From Brickwiki
Juniorization is a term used by Adult Fans of LEGO (AFOLs) to both describe and criticize the inclusion of a few highly specialized elements in sets instead of already existing elements that could be assembled into the same configuration. A BURP (Big Ugly Rock Piece) might be considered a juniorized element but it is more common to refer to pieces such as
which is simply an element that reproduces five of
stacked together. Juniorized elements are simple (ie: not complex) POOPs.
The major compliant is that this practice reduces the possibilities to build alternate models, a cornerstone of AFOL activity. Some AFOLs however revel in the chance to use these elements and consider their inclusion in MOCs a challenge.
The Jack Stone theme, aimed at younger builders than System themes, was heavily juniorized and was particularly unpopular among AFOLs.
Another juniorized element was the BFC piece (Big Freaking Castle).
