I'm a big fan of xenosaga it is just way out there more like watching a movie than a game. I have xenogears and just got stuck fighting this one battle and am not on a talking relationship with that game now.
However, I did see some kosmos in seattle and really think it is a great flashy outfit, if I remember to not forget my camera and kosmos is at kumoricon this year I am so going to have to get much pictures.
