Enough rules to make the game work, but not so many that they get in the way.

This is an excellent "middle ground" between the classic 2d6 system (which was in some places a bit sparse and lacking) and the current versions (which are in many places too fussy and unnecessarily complex, or suffer from contradictions and clarity issues). Think of it as the classic system which has been enhanced, introducing some new ideas and incorporating some of the better ideas from the later versions.
