It really is worth your time. There are problems, though. There is no real turn-based system. Combat is really hard, and dialogue can just drag out awfully. Serious problems with your character, such as energy drains, are much too subtle, and may be overlooked.
Load times can be rather long, too, and changing discs constantly is a real pain.
Graphics may or may not be good, depending on your system and configuration. The main thing in most RPGs is battle system. Surprisingly, this RPG has significantly less battles than most other RPGs I've played. The battle system, however, is different for each character class. For example, Breach may be used three times per day, if it is copied into three different slots.
