Actually, there is an issue in BM culture.
Nepotism.
I swear, the same players play together all the time. I try to be careful to mix it up some; I've played as an ally and an enemy to Anarises, Bedwyrs, Solaris, Chéniers, Lefanises, and many other families. The only prominent families that I have played with in multiple different circumstances that I have always been an ally with that immediately come to mind are Perth and Keithson.
I think if "old" BM players would work harder at destroying, IC, their OOC friends' characters and building up, IC, their OOC "not-as-much-of-friends' " characters, it would go a long way.
In other words, we should force an Anaris, Chénier, and Lefanis to all play in the same realm. For a long time. And work together.
I've played in the same realm as Lefanis with many characters and for extended periods of time.
That was enough.
As for Anaris, circumstances have put them regularly in realms opposing those I've went to. Result of circumstances, really. Took me quite a while to associate Anaris with Riombara, as in my earlier years a realm was a thousand times more important than the person ruling it. I OOC wouldn't mind it though I have a hard time seeing cooperation IC actually working out.
And by the way, none of the OOC friends I've brought into this game, or who brought me into the game, still play. Any friendships my family and characters hold have been developed purely IG. And I've never been one to turn people who want to help me away (except if that character pissed off another of the family or if the family as a whole has a bad history with mine). I have never marginalized newer families because of their youth: indeed, I tend to find that they make better allies, because they tend to be a lot more eager to prove themselves.
But really, how's nepotism an issue in the BM culture? I can imagine it being so in some cases, but not in most places I play. The realms I play have tons of positions attributed to the single person putting his name in the referendum for it. Yea, I tend to be at the top, and yea, I tend to take up a lot of power... but that's because I don't see anyone who actually wants to take that power. I'd rather take the power and make something of it than give it to someone that doesn't really want it and won't do anything of it. In the past, when ambitious people were more plentiful, I used to want to limit myself to one or two titles in order to satisfy the greatest number of allies possible. I don't really do that anymore, but it ain't because I've become greedy or power-hungry.
Years ago, I had to constantly struggle to increase my power or influence, and put great efforts because the old guard seemed to universally be, everywhere, considering me as a trouble-maker that threatened their hard-earned titles with propositions of such silly things as wars. I always feared that, years later, I would become like that, and that having achieved my power I would crush all those who challenged me, and I promised myself I wouldn't let that happen, that I would use my power to promote fun instead of stifling it. Maybe my strategies work, maybe not, I can't really say, but I can say that I don't see anyone running around even remotely resembling what me and the people I associated with. The other challengers to my powers are not people close by would would like what I have gotten, but people far-away who would rather I be more quiet and docile or have strategic interests against me or my realm.
Note: I'm also not sure what making all the established families working together would accomplish? We could organize power structures that would create invincible alliances, until all the rulers of the continents we play together on are friends? I don't see what the fun in that would be.
