If people think they are going to be 'rated' on games that they have
previously been told, don't count, there is going to be a chilling effect
that discourages people from participating on the website here.
For that reason, two separate rating systems should be used, if at all any
ARE used: one would be for those adventurous souls willing to play games
they've never even heard of (and are therefore attempting to learn), and
another rating system for those souls that insist on playing just one
particular game, something they actually know a thing or two about, and
about which they have developed theories of play that are put into
practice.
