I love character creation. I can happily fiddle with sliders for hours trying to create something I'm happy with (and get a sense of their personality while I'm at it). Dragon Age is a good place to look for customisation, though I gather some other games have recently done an even better job.
We have the usual starting point: male or female? I've recently been spoilt by Demon's Souls which has a slider bar for gender, allowing you to be androgynous or anywhere you like along a spectrum. I thought that was pretty awesome, and I sighed a little at returning to the binary choice here. It was expected, though.
