Menu's is something I always wished I could do better, but I can google my ass off and still not find a good tutorial on sweet motion menu's, maybe someday Ady can share some of his techniques with us, I know I would read it a few times.
Although I will admit, I hate them if they are to long, but if they are to long, at least have the option to skip and go right to the selection screen, I do not like HAVING to sit through 2-4 minutes worth of menu before selecting play, that is to much.
