The Weight of Complexity

Given the importance of actually communicating with one another using words which have a shared mutual understanding, I remain amazed that the word "weight" remains in frequent board gaming parlance without having been split or somehow qualified into several different terms, because there are so many different ways of understanding it in relation to gaming. The problem is illustrated easily by the game Go: to me, Gois a heavy game because it demands intense concentration during play. To many other people (and this is illustrated by its weight rating on BGG) it's a light game because it has few rules and is easy to learn.
