Just F-ing wow.
Had the pleasure to run into the catacomb location as the first person there, and... I was blown away.
Whomever designed that area should receive a honorary invitation to any game design company.
The oponents are perfectly chosen. There are oponents resistant to slashing damage. There are oponents resistant to bludgeoning damage. There is a fight against casters. Attempts to loot the placeables are sufficiently random to keep you entertained (the peek-a-boo from within is a very, very nice touch!). Traps abound sufficiently to make my "Wee!" run turn into "Oh, shi-!" on the first corner (my first and only death occured 10 seconds upon entering the area
The culmination of the quest is just excellent, with the ability to choose one's action. Unfortunately for me, Curtis has a tendency to hack everything to pieces (including bodies lying on a certain altar), so I was not able to get all the way through the evil-path (figured he'd be swayed by the possible gain of power enough to do that rather than just leave those things alone). Of course, having the ability to attempt to lie to the father at the end (with bluff skill in negatives) was also an amusing touch.
Definitely plan on repeating that quest, hopefully finding the area in its pristine state again.
My grateful thank-you to whomever managed to create something that kept me way past my bedtime
That place is simply a work of art.
