Develop have a short piece with Josh Sawyer on the NWN2 toolset at GDC in Paris.
More information."BioWare's approach to the Neverwinter Nights toolset was to go for ease-of-use, so that people could get small things running quickly and then expand from there," said Sawyer. "Obsidian's approach was to cater for the hardcore, though - dramatically increase the level of control, meaning that more things could be altered. That would make the barrier to entry higher, but we thought that would similarly raise the quality of what was produced."
