I think a lot of people who make area prefabs or such, can get great ideas from this hak. Make more quick variations to your area prefab and change them to look the certain seasons.
I�d like to see scorched earth get made for NWN 2. And the Undersea too, maybe have an underwater adventure like in Pirates of the Sword Coast. Make sure to give the characters a ring of water breathing and free action to prevent drowning.

Really and truly, I mean *absolutely no offence* by this - but I can't help but wonder: if you like NWN1 custom content so much, why not just play NWN1?
