People complain that Amarr and Caldari RP is dominating, and that Gallente and Minmatar RP is nowhere to be found.
I had a thought about this.
For Amarr RP, there is a substantial amount of what people call 'internal' RP available - the methods of the Reclaiming, the treatment of slaves and commoners, the politics of Holders and Family rivalries, and so on.
Any Amarr character can join the internal factions, with fairly little difficulty. Swapping between factions may be slightly more difficult, because of oaths of fealty and so on, but it's not necessarily impossible.
For Caldari RP, the most obvious internal RP is the Megacorporation system, where the different megas will have disagreements and rivalries. There's also the foreign policy factions.
Again, any Caldari character can join any internal faction with little difficulty. In fact, Caldari might be able to move between internal factions with greater ease than in Amarr RP. It's simply a matter of changing employment contract.
For Gallente RP... the internal factions are difficult for me to pick out. There's voting blocks that are mentioned in chronicles and such, but they're not really obvious ingame.
Anyone can join Gallente RP, anyone at all, even non-gallente characters. You can be who you want to be in the Federation.
For Minmatar RP, then, the obvious internal RP factions are the Tribes.
But, a Sebiestor cannot join the Brutor Tribe. Game mechanics mean that you can only choose between 3 of the Tribes, and the poor Vherokiors get sent to Native Freshfood, instead of Vherokior Tribe. Why?
There's no real way to be a Krusual Tribe supporter, because you can't make a Krusual character. You can claim to be adopted or something, or a half-Krusual half Sebiestor or something. But by the game mechanics, you're not.
This makes a hard limit on being able to move between internal factions, and with only 3 actually represented by character creation choices, then it makes it a lot harder to set up internal RP.
So, that was my thought, on why Amarr and Caldari RP always seems to be doing better than Gallente or Minmatar. There's enough stuff for people to form internal RP, and to keep it going, through occasional changes in loyalties. A gentle stir every so often.
