One need only look at the fact that the Play Station 2's Special Edition is made up of two discs (one with an English dub and the other with the original Japanese dialogue) to see just how much info is in this game. That's why it's such an interesting and, frankly, amazing experience, though.
There's another reason for the initial hesitancy: this is a SEGA game, made by an internal SEGA team, and that originally only appeared on SEGA hardware.
The series eventually moved to the Play Station 2 when SEGA's hardware business crumbled, but the post-Dreamcast publishing environment was even less of a risk-friendly option in the early days, and thus, the series continued to be successful in Japan but only accessible to an American audience with a decent grasp of the Japanese language and the fiscal means to import things.
"In the midst of cleaning Akademi High School, you stumble upon a bloody knife in the Occult Room.
Not wanting to get in trouble, you stick the knife in the Occult Club's skull figure, but you wind up teleporting to a place you don't recognize.

Sakura: I-I mean, no one will see the blood, if it's in the skull, r-right?
