Well, rather than explaining the previous, an example (with answers included), perhaps to encourage other question makers.

Frayster:
1) ruler
2) blueblood
3) beggar
--------------------------------------------
Answers:
1) Historyguy - originator of the fray rules schtick, but also preeminent frayster hereabouts for quite a while.
2) Seasquirt - seasquirts do have blue blood (arguably too easy), and, of course, carrying on with a theme of early BOTF leaders, which leaves only:
3) Ender - method of starring, but also I like the social structure implicit (Ender is the beggar-king, or, at least, beggar, noble).

As for "parsimonious" - quiz: Am I crazy (read: too in my own head).
I'd say "parsimony" is making more of less - elegance in science, or poetic language, often. Thus, a title like "parsimonious expression game" is a tiny little bit funny since "parsimonious expression" is a rather unparsimonious expression (I could'v just called it the parsimony game). The additional joke is that gene expression is parsimoniously coded, which is one of the surprises of the questions I asked (hint). Just some idle fun, but not fun (and crazy) if like a certain lunatic elsewhere, I am not being communicative. What I expect, more, is for respondents to explicate as if it were a novel point - e.g., an enjoyable response to a post would've been "dummy, a better title would've just been parsimony game". I'm currently in the negative in my entry, and for this justification/explanation of my behaviour (more properly a response to Isonomist's thread above), I subtract, mmm, 100 points.
