Well, I can help you with alignment thing, seeing as how gamer/computer nerd was a close second for me. :P In Dungeons and Dragons (or any sort of role playing game) your character has an alignment. Like, Chaotic-Neutral (don't believe in good or evil, or an inherent order to anything) all the way to something Lawful-Good (honor and compassion and playing by the rules!) to Chaotic Evil (screw everyone and everything, it's all about ME ME ME!). It's sort of a guideline for how your character would react in any given situation.

And now that I have out nerded everyone on the planet, I am off to do something outdoors in penance. Lol.
