Throwing in a rather harsh opinion:
It's about as exciting as banging your head against the wall. I also heard some rumor about it being against the Geneva convention, something about inhumane torture (maybe not that bad).
All humor put aside I felt that from beginning to end almost each chain was about finding a single person/object/archive/treaty per planet. This meant that each individual quest on a planet was about storming a random bunker/cave/facility/archive only to find you "just missed" your target (princess is in another castle). Rinsed and repeated "barely missing your mark" about six times until catching up at the end of that planet. All chapters used this style of progression and in comparison to other classes, the whole shebang ended on a whimper.
The plot moved at a snail's pace the majority of the time and jumped forwards exponentially at the end of each chapter, with exception to the third. Any big revelations were very predictable. Lastly, unlike the other arch-types, the conversations are dull and lacking any hint of entertainment to illuminate the way.
In other words... good luck.
