Up until very recently I just did an approximation of myself, but I'd still always spend like 2 hours on the character creation. I'm getting bored with that now, so I've starting making originals. Highlights so far include making a [whatever the giant race is called] woman in the FFXIV beta and striding around the starting area twice the height of everyone else, and trying to make as female-looking a man as possible in Skyrim (and having some success) and not wearing anything but robes.
I also made Hugh Laurie in Saint's Row 2 once.
