I made a couple for NWN2. Aside from some very limited modding in Morrowind and Oblivion (on the level of simply deleting Creeper) they're the only mods I made from any game. Two playable adventure stories, The Corruption of Kiahoro and Traveller which were quite well recieved, and a character creator which no one gave a crap about.
I'm not doing any more. They take too much work and I'm all out of ideas. Plus I'd rather play games than make them. But I'm very glad I made the two I did. I'm very, very proud of them. They're the best, most worthwhile things I've done in my life.
