I picked this game up recently and it is really fun! Have any of you played this particular MMO (or the offline story?) This is the first Phantasy Star online game I've played out of all of them. If you do play this game, what system do you own it for? and what is your favorite about PSU?

My favorite aspect of PSU is having a variety of weapons and being able to modify them to make them stronger and attach photon abilities to the weapons to provide extra attack. The missions are pretty fun as well, it would probably be even more fun with other people if I actually got the one that I can play online (I have the PS2 version with no network adapter).
