It's not every day that you see an expansion for a 23 year-old game, but thanks to its undying community, Neverwinter Nights isn't just any game, with a level of support and fanmade content that calls to mind the likes of Doom or Thief.
With the blessing of Wizards of the Coast, fantasy author, RPG developer, and Neverwinter Nights enthusiast Luke Scull has released Doom of Icewind Dale, the first act of a sequel campaign to Neverwinter Nights, as an official $10 expansion.
Doom of Icewind Dale is set some years after the events of the original NwN campaign, and promises 10-15+ hours of mid to high-level third edition D&D questing in the Forgotten Realms' notorious icy waste/adventurer special economic zone, Icewind Dale.
Rounding out the value, Doom of Icewind Dale introduces new monsters, portraits, music, and a narrated intro sequence to set the stage.
BioWare's Neverwinter Nights is an incredibly weird little RPG that was somewhat compromised by an identity crisis at its core, but in a funky, interesting, old school RPG way that only makes me love it more.
