Hi Genshou,
Frankly, I think "elegance" is a pretentious term suimilar to that typically ised by art and antique dealers, "important." Elegant is not a quantifiable thing, it is an opinion and value judgement, as is the term important.
Very ofter I find "elegant" used to laud some truly bad or dull game that only a handful of persons will ever enjoy playing, but some "important" critic/reviewer happens to like, or thinks he should like.
I think if I say more I'll be in trouble with the clique that claims play of RPGs is an art form:
"Yes, Dear Fellow, you play that game of make-believe so artfully..."
Cheers,
Gary
