The official campaign was good, but some user mods are far better. The best way to experience these mods is to play them. However, there are some things that may not be as easily reproduced. Here's some.

Delicious dinner

Them Goblins in the Cave® sure had a delicious dinner that day: roast beef with sawdust. Mmmm... yuck.

Painful point blank shots

This module involved some Violence, even against one of the famed cunning and evil drow leaders of Cormanthor, Jezz the Lame. I'd like to point out that this particular shot was a honest mistake. Even though the point was to kill Jezz, this was a far too brutal way to do that.

Truly epic fights

SoSD was the first module I played with the camera hack. The thing made quite an improvement to the immersion: The bow fights got quite a lot more amazing. There was nothing more surprsing than a shot from the dark, and killing advancing orcs with the bow was, truly, epic to the extreme. Here's some dying derro. By the way, yes, NWN arrows do have ballistic trajectories.

Very First Test of the Memetic AI

If the Memetic AI gets used more often (this module actually doesn't use it yet), we will next see orc warriors who loot to the tune of "all your base". =)
