First off I love the first pathfinder. I will most likely never use it as an adventure, but it was a fascinating read (kinda like a good book), and I was able to grab some traps and creatures that I will use for upcomming adventures.
Personally I love dark so it didn't bother me, but it definately wasn't suitable for younger children. Maybe a rating in the product description?
While copying the stats for an adventure later this week I noticed something: The goblin snake has an initiative modifier of +8. Dex gives a +2 and no feat or special abilities are listed. Is this a typo or was some ability that granted it a +6 initiative accidently cut out?
I'm not sure if this is the appropriate place, but I don't know of any errata page/file for pathfinder products.
