A recent question about a good mix of board games got me thinking about how one could even objectively define "a good mix".
My idea is to try and define a set of attributes that could describe, compare, and contrast various board games. I hope this exercise will help me discover some attributes unrepresented by my gaming experience and achieve better insight into the common elements of my favorite games.
An example attribute might be inter-player cooperation, which would slide along a continuum from fully co-operative to team-based to free-for-all, with arkham-horror axis-and-allies and risk being examples of each type, respectively.
I think answers could either work as one-per-attribute (with votes for ones that make sense) or as a comprehensive set of attributes (with votes for the most thorough and complete answers). Comments seems like a good place to flush out the pros and cons of each approach.
