I've only played the first .hack game after I got to the final boss finally after an hour of beating him down did I data drain him and then he blocked my use of magic after I used all my potions up already I was a little pissed and threw the game into the depths of my closet, though I have been thinking about playing the newer one, it catches my eye everytime I go into Game Stop.
Btw I love KH SOOO much, favorite game actually. My fav person would have to be Sora though he's my boy. ^_^
