A game geared toward beginners ...
Beginners at Civ, or beginners at PitBoss?
And I would assume not defined by time since first game, but by level of accomplishment. So assuming you mean a particular Civ skill level ...
You might exclude anyone who has ever beaten monarch in SP, for example (or pick you level).
Or exclude anyone who wins more than half the time at monarch in SP (or again, pick a level).
Now, since war is so crucial in PitBoss, maybe need some sense of military skills? Harder to assess.
Who is the target population for such a game? Are you trying to entice other
TG members to try Civ? Or are you trying to entice SP Civ players to try PitBoss?
For the latter, the CFC GOTM forum (game of the month) has a lot of players reading it who might meet your "developing player" category ... so that might be a place to market something of that sort.
Bernout, when you say pair people up, do you mean have a team game (civs in teams)? Or are you thinking of combining pitboss with the succession game concept?
The latter would have appeal to me, as one limitation I am finding with PitBoss is turn order issues during war, intersecting with my rather fixed play windows in a weekday. Having two people playing one civ, with an honor code that each plays half the turns on average over say one months time, would make keeping to turn order easier, provide automatic coverage for vacations etc, and be a great way to have a training camp for beginners while still letting the wise old veterans be involved.
We could call the concept PitSuc ...
