On another note, regarding scenarios. I'm at a crossroads with them over giving away details. 

Would it be best for me to provide: 

[list]- General layout
- Types of monsters present, if any.
- Lore-related discoveries (i.e ancient texts/pictures denoting Ironshore's past)
- Loot to be found.
- Weather
- Time of day[/list]

Or would it be better to allow the players to decide? You know, let 'em make it up as they go along?
