Someone should figure out how to quantify how “creative potential” a piece has so you can measure how reusable pieces in a set will be for building unique things.
I suspect you’re right, and would like to add that perhaps the physical weight of the piece may also provide some insight. Small light weight pieces with many connectors likely have large amounts of use cases. Big pieces with small amounts probably not as much.
The axis upon which connections attach to may be another important variable.
