Here is a quote from creator Takao Miyoshi from the E3 interview:

"One of the recommendations I have for the fans is to play through PSU's story mode first so that you can really enjoy the game. As you progress through the story, the characters can be customized and you'll get to know more about the playability of the characters, as well as the other elements and features in the game. After you've done story mode, go online and play, it will be much more exciting. When you go online, just enjoy the experience of exploring all of the storylines and features. As mentioned, I think of PSU as a long project, so enjoy the game as long as you can. "

Who is planning on taking his advise?
