Oh and I'm pretty proud of myself. I'm about 35 hours in and level....18 I think? I like to wander and explore and refuse to use any of the Ritual Stones that make you level faster.
I've only used the Steed stone (allows +100 carry weight and removes all penalties for wearing heavy armor), so that probably is the reason why I'm only 18.
Anyway, I have the CE version of the Game Guide and only use it for minor stuff that doesn't ruin any of the surprises (like looking at a quest AFTER I completed it) or determining if a dungeon is quest related or not so it doesn't ruin said quest.
Plus, it came with a code to gain access to a pretty incredible interactive map that lists every single thing in the game, but haven't used it. You can show as much or as little as you want on the map. Pretty damn cool.

All this will be used on my 2nd and subsequent playthroughs, just proud I'm not using it hardly at all now. The exploration is what makes the game so fun
