1) Will the encounters be scaled to the players level or of static difficulty?

RR: The ability to scale the encounters is there much like NWN1. For the single player campaign, though, we know how much experience the character could possibly have and make sure encounters are the appropriate level.

If the player wanted to play the single player campaign again from the beginning with a level 20 guy…Well, I feel sorry for the Goblins because they will get a fast trip to the hurtlocker.

However, if someone wanted to change the module in the ToolSet and have it scale accordingly it would take into consideration the level of the character(s), the size of the party, etc.
