I think the game could definitely do with some polishing up at and beyond the Nameless Isle. There needs to be MORE skills, that is new skills, and the skill-crafting system needs to be reworked and improved, as does the regular crafting system.

Plenty of broken or odd quests in Arx, and the balancing there is quite poor. I literally didn't find Anathema until after I had already beaten the game, I had to go back on an old save and spent about 4 hours or so exploring the entirety of Arx until I found what I had missed.

I still haven't found the Voidwoken route, it might have been on the Nameless Isle via the Sallow Man, but when I encountered him, he immediately looked at Ifan, Ifan looked at him, Sallow man says 'You...die' or something to that affect, I can't turn in Alexander's head, and will never find out if it was that or something else, though supposedly there is such a way.

The option to flood the entire City was Deathfog was pretty cool, the random Deathfog crates in that fight area were not. The instant killing deathfog spider wipes out 3/4 members of my group...and later down there, one of the undead Guards uses a crate to kill multiple members of my team again, requiring me to resurrect them and use a tornado to clean up the deathfog.

I just really didn't enjoy the third part of the game.
