I think the problem is that people read the description of Minmatar, go "Oh cool! Lone wolf biker rebels!" and roll with that, and many become pirates, work for other factions, and other such "anti republic" angles. There arent a whole slew of "Anti Empire" Amarrians, and there certainly are a teeny minority of ones who preach abandonment of everything Amarrian, yet, that is precisely what the plurality of Minmatar ethnicity characters tend to do. If everyone in minny society was a "lone wolf", it wouldnt be a tribal society; it would be, well, exactly what RP depicts. I did midsummer events for the past 2 years, big Minny-centric parties. The first one had an OK turnout of maybe 20 people, I think 2 or 3 of whom were Minmatar. The second? I think 8 or so people came, and zero of them were from my own corp... and I think I had one other matari attendee this year, and one or two the first year. How many people show up when PIE throws a party? Oh, keep in mind, those two events are the only remotely Minny-oriented RP I had, save the odd short conversation in Summit with a person curious about religion.
I'd love to play eve again. I miss it. But I know all it would do is frustrate me, as everything about Minny atm just sucks. And frankly, I lack the resolve to try and "fix" it anymore. I've been trying for a long, long time. Suerte to whoever decides to pick up that torch.
A tribal society (and hence, RP) tends to only work if, you know, more than 1 person is involved. It grew lonely.
