I like the two-swords, and the ninja styles the best. Fast, powerful, unique, and cool looking. I also liked the other weapons besides the swords, like the naginata and that thing from the first game that had a blade on both ends. But really, I like all the different swords and stances.
in the first game mine was low stance. The sword I used was Okhotsk I believe. It was the red one and you could do all these rolls on the ground with it.
In the second i used fencing stance. The sword I used was the Zannkimaru because it looks freaking awesome. I also used the Biteikotsu which is a one handed sword which looks deadly and also has some deadly ass attacks
all this talk makes me want to play these games again
