How do I determine my character's non-pod RP power?
Via the "how can this shit sound convincing?" rule.
Vieve's beginnings were similar to Saxon's, minus the whole Intaki and Syndicate bits and likely a fair bit more.
I never intended to RP in EvE. (Never intended to join a corporation either, but that's a whole other story.) I created Vieve after a year of short-lived Caldari alts, most of which'd been tossed for some vague reason or another after a few months of life. The very last Caldari alt of that batch'd had gotten her ass repeatedly handed to her by Gallente gankers1, so it dawned on me ... hey! Maybe I should try a Gallente character!2 That way I can roam around and look at things wherever I want without a problem!3
So, I created a Gallente combat pilot. Tadaa!
A week or so in, after I'd gone through the FNA and CAS tutorial (I'd learned enough as a Caldari alt to know that industry skills were useful) and was preparing to head out to an unfortunate part of Essence to start FIO missions, I ran into this new Caldari player named Ana Kerst.
She'd gotten one of the random "personalized" Strix recruitment e-mails that Gervais used to send out, and felt she needed some advice on how to respond to it through a RP perspective. Since there was a "Vieve Tisserand" in Balle local, looking all Gallente-French, she took a shot on my knowing about this RP stuff. She opened a chat and started RPing a flustered researcher type at me. No warning, nada.
As with many things I've encountered since, the right answer might have been just to say "go away, you freak!". But I didn't. I rolled with the dialogue and the stuff I pulled out of info windows and Google. Vieve started her IC life as something like this:
"How do I know all this about Strix? I grew up in the capitol, and you really have to work at not knowing things about the government if you grow up there, especially if your folks ... ah, Maman's a Senate science policy analyst4, and Papa ... honestly, I'm not sure what he does. We don't talk about his work, and I'm not sure I should be talking about that with a Caldari, especially if she's not a traitor. And you said you weren't a traitor, right?"
Things sort of devolved uphill (or evolved downhill) from that point, usually via improv in response to questions brought up during interactions with other players.
1It didn't occur to me at the time that my adventuring around low and null sec might have gotten me pegged as an alt scout/spy.3
2These being the days when one's choice of race and background actually meant a damn as far as what skills you started with.
3I never claimed I was smart.
4Since my employment history includes stints in joint government/private industry/university engineering, science education and international economics outreach programs, I figured I could fake being a "Federation Senate science policy analyst" enough for EvE purposes, if I ever had to. Never thought I'd need to. Silly me.
