I'm just a good-natured, soft-spoken guy, and I almost always go for the good side of the alignment table. Specifically, it's usually just chaotic/neutral good, depending on my charm/charisma levels. Lawful good is for pansies. Going to the evil side of the table implies some insanity, or at least some kind of unrelatable sociopathy.
And this goes back to the problem with good/evil morals in most games.
Being bad typically amounts to you being an angry jerk-ass for 90% of your waking hours. "There's too much salt in this soup. I hope the chef is prepared for the most amazing ass-whuppin' he's ever seen."
On the other hand, being good usually does NOT make you into a halo'd heaven-sent do-gooder (except in the first Fable, where absolute goodness gave you a literal goddam halo), but instead makes you a charming, likeable good guy who helps out and wins with words more often than a fist. "Now I know you want to fill me with so much lead you could sharpen my head and call me a pencil, but have you considered how much easier life would be for everyone if you didn't shoot me, and instead opened up an orphanage for children and puppies and kitties? Yeah, I knew you'd see it my way."
Ye gods, that was a bit of a tangent. Anyway, yeah, I'm the good guy in real life, so that's what I am in games, too. Shoot, I TRIED to play renegade Shepard in ME2, but it didn't feel right at all.
