I bought Arx quite recently to quench my thirst for a challenging part-RPG, part-adventure game and so far, I'm having a blast. I love the quirky magic system and the puzzles are very well-designed.
I've had my fair share of interesting moments, ranging from scary encounters in the Crypt to the challenges faced in the Temple of Illusions.
When I was playing through the crypt levels, I came across a room where the statuette heads follow your movements. I did not notice that at first but found out after I turned to face one of them after a grueling encounter with a zombie. Boy, did that make me jump!
What experiences have you had? Perhaps, discovering that a certain goblin suffers from diarrhea or that a peculiar troll appreciates the world that once existed above the ground?
