Few things are in shorter supply than proper dungeon crawls with traps and puzzles, and I personally find those aspects requisites for doing it right.
I'm genuinely excited by the potential of this game, and trust me, that doesn't happen often anymore.
The last game that completely absorbed me was Gothic 3 - until I finally gave up in frustration because of bugs and a lousy combat system. There have been great games since that time, but the free-form genre has never been done better than with the Gothic franchise. One of the few weaknesses of Gothic 1/2 was actually the lack of meaty dungeons with this kind of content. The dungeons were always great looking, but were mostly just full of monsters and I don't remember anything like real traps and puzzles.
Wonderful news.
