Like seemingly everyone in this thread, CC is very important to me in any game, but even more so in TSW. So I hope they do an awesome job.
I watched the APB cc, and while it certainly showed amazingly cool stuff (the tatoo and cloth-print thing), I was kind of let down by their body editor. It didn't seem you could edit the height of a character for instance, nor go for real extremes. They were all fairly average to muscular.
The height absence could be due to that characters in that game interact with cars a lot and maybe different heights gives clipping/sitting etc problems in that respect.
Anyway, I'm hoping for lots and lots of options. More than any mmo has had so far since the personality you create in TSW seems to carry so much more weight than your usual mmo character (does anyone else feel that way, or am I just being weird? :P ).
