considering that you can already get the dooku opening stance, that coleman and obi-wan both show the same stance for two different styles and that the juyo stance can be found in the pack already, i dont see any of these as adding the game. Also, and max, DD, or anyone correct me if im wrong but, we cannot seperate the dual stance from ataru and niman from staff.
heres an idea that would add the game(dont know if its at all possible tho), each style should have X amount of stances to choose from. each player can choose their preferred stance when they buy the style. i dont think its possible tho do each player having their own animation cfg with commented and uncommented stances.
