Just curious: how do some people come up with their character's back-stories?
Here's my process:
Mine is the direct opposite:
First up I've never played a woman in anything I've played. No idea why, but it's basically tradition now.
So I go - What do I want to play/What does this group need more of - that gets me my class.
Then I skip straight to the backstory. I throw a complication straight on the empty table and away we go.
Complications: He's an idiot/He's rash/He's pretentious/He's insane/He's uncompromisingly evil.
Put that in, and let that guide the stats you make for them. Chances are you can still minmax them pretty effectively whilst working around that.
After that you try to figure out WHY they have that particular character trait
Are they insane? Maybe something horrific happened to them or their family.
Are they stupid? Maybe they've lived a very sheltered life.
The GM usually gives you a reason for being there, so you just tweak the last year or so of your backstory to shunt in there as needed.
From there it's just filling in the little blanks with dramatic/funny stuff as needed and away you go.
My personal two triumphs would be:
The Xenophobic lizardman paladin I created for a high-rp game I played.
(Humans were spreading throughout his home swamp which would usually have been anathema to them, so he considers them some kind of highly-adaptable vermin)
- And a funny half-orc berserker who grew up with a very soft heart and lawful mindset, underneath a very evil and manipulative baron von father figure.
