I have written for several RPG games in the past, and some of it actually saw the light of day! Below is some of the work that was done for Bioware's Neverwinter Nights - some as a professional, and some as an amateur.
Wyvern Crown was the final expansion (or premium module as they were called) for Neverwinter Nights. It was developed by DLA, directed by Robert Trifts, and produced and written by B G P Hughes.
It is currently available from sites like STEAM, GOG and Fanatical.
