regret making it to be able to live way beyond their desire and usage. NWN was never meant for persistent worlds. A lot of things are not done well to support it. But the community did it. And a lot of things needed to be fixed in hardcode.
I believe "the last official patch" should be 1.66 as diamond version came out. And they did it just because the game was still played a lot. They didn't want to make any other support they said
But they were forced by community to every and each patch after that. Not many games gets a huge patch 6 years after original release.
I like even the campaign. Playing it time to time. It is good. It can be considered weak only when compared to what people made in years after release. Still waiting to some game with at least similar possibilities.
