NWN was a high water mark of mod tooling focused games. Map editor, DM Client, scripting engine with DB hooks all as part of the base game was really cool. Some of the micro-Persistent World communities that were built out are still running today. Hopefully that kind of thing comes back around eventually with open-source game engines, etc.

EA slowly drained all the potential away until they were just a shambling shell of what they once were.
