RPGDot has published an interview with Obsidian Entertainment's Chris Avellone and J.E. Sawyer, in which the RPG veterans discuss their upcoming Neverwinter Nights sequel. A teaser:
Q: Speculation is rampant about the strongholds that will be included in the game. What can you tell us about them? Are they class-specific? Can a PC own more than one? How do they work?
A: The player has a single stronghold, and it is not class-specific, although some of the things you can do in the stronghold may have different effects depending on your class and alignment. Without giving too much away, the Stronghold game mechanic begins with you given a shell, then you have to spend and gather the resources to build and upgrade it however you see fit. Some of these may involve searching the world for recruits, others involve completing certain quests, others involve spending a few dozen bags of gold or so.
