I figured that was probably the case. See I was wondering about these things due to Phantasy Star because those morons at Sega didn't make it online. Sad thing is PSU requires online to have any fun elements to it as single player is basically like trying to do Guild Wars or WoW offline, by yourself, and in some dungeon area where you go maps deep with a very poor map so you get lost quick and forget what you're even bothering.
Tales of Destiny that has been out for a time on PSP is just like that and i couldn't tolerate more than a few hours of it as it has a good story unlike PSU. It saddens me, but at least Phantasy Star Zero for DS has a good story and online wifi and comes out like in 6mo~. Oh well at least I save $40 I can use towards Prinny or Ys Legacy on DS, or maybe Dragon Quest 5.
