Since we seem to have covered all about CC systems and customisation there is, let's look at another aspect of customisation: Voices. It's been a few years since I started playing video games, and those years have made me hate silent protagonists with a passion. The only game I can think of where I could overlook that fact was Fallout 3. That game was so damn good.
I'd really like it to have the option to choose different voices, like you could in SR3. The ability to adjust the pitch of the voice would also be nice, as would a few different acccents (Russian, French, British and German come to mind). Thus. being able to make a suit-wearing villain with a german accent and black shades... or maybe I'll make him british, who knows?
@ braindancer12: Jack is wearing clothing now? Has somebody caved her head in in beteween ME2 and ME3?
The thing about the hairstyles is: having a few premade ones is nice, but having an interface to make hairstyles of your very own would be even better.
