My Fallout: NV exsperience has been ripe with roleplay, all my characters so far have had their own unique personality (ya I got multiple characters); my current bro is a hardcore law-bringer, destroying injustice in the Mojave, but he has taken up the hobby of boozing after his hubby (Veronica) was blown away by some fiends.
 
So ya I was just wondering what other peoples roleplaying exsperience have been like.

My character is a badass, mustachioed gunslinger, looking to bring some justice to the wastelands. Also he's a scientist and he knows how to get himself out of any sticky situation using his superior intellect. 
 
He's a racist though and hates ghouls.

I don't role play in that sense. I ask myself what I would do in the situations presented in the world and context they are presented in. 
I role pleay myself. And I'm a pretty lawful, but opportunistic do-gooder, as I imagine would be in a harsh, post-apocalyptic Mojave wasteland.

I always role play as a fresh recruit marine that has been tasked to save the planet on his first mission. Sometimes I customize him bald to make it more personal.
