More add-ons for stance/walk/run like the ninja pack would be wonderful and give more versatility to characters.
My ideas so far are...
Sports pack - add rollerblades and skateboard with a roll animation instead of walk and a few more sporty costume parts.
Creature pack - adds creature crawl on all fours stance creature costume parts, and maybe a short wall crawl.
Robotics/Droid pack - adds crawler and tank treads lower half and more less humanoid robot costume parts.
