The Premium Modules previously reported for Neverwinter Nights are now offered, for a limited time, at a reduced rate at the online BioWare store. Shadow Guard and Witch's Wake now collectively cost $1.99 (USD) while Kingmaker can be purchased at $5.99 (USD) or $3.99 (USD) depending on whether you purchase the full or the lite - no voice acting - version of the module.
Kingmaker, in addition to being the largest of the new content sets, has recently been nominated for RPG of the Year by the Academy of Interactive Arts & Sciences. Although there is no specific date set for this price reduction to end, BioWare has advertised the event as a "limited time offer." Any further information regarding Neverwinter Nights or its upcoming sequel will be reported as it is received.
