Weird thing is i can see the butt slider thing happening way before any other "sliders" lol. Yoshi did mention if people would be ok with slightly stretched textures if it meant butt sliders and some ppl seemed ok with it (similar to how they went about longer hair, they asked ppl if they were ok with some clipping). That said, do not expect korean MMOs levels of butt though, if they make a slider it will be pretty much in line with any other currently existing slider :P

and yeah the muscle slider should be realistically called a "tone" slider instead XD
