NeverWinter Nights must had been the most anticipated RPG ever. Following in the wake of Baldur's Gate games' artistic and financial success, our appetite was whetted for a third-person cRPG set in the Sword Coast of Faerûn. Because there are tons of reviews on the individual games (links provided), I shall focus mainly on this NWN Collection itself.
Note that the Premium Modules collection is not complete. Three are missing: Infinite Dungeons, Pirates of the Sword Coast, and Wyvern Crown of Cormyr. They are probably missing because they came with DRM that required ...always OnLine authentication (they have been pushing this for years!) - and EA took the servers down once they had been hacked at least once. Still, one would expect, after almost a decade, that the missing modules could be included in a DRM-free version. Disappointing.
NWN II SAGA: This collection contains the original NWN2 game together with its two expansions, Mask of the Betrayer and Storm of Zehir as well as its adventure Pack, Mysteries of Westgate (previously only available via digital download).
NWN2 was initially released with a number of problems, the camera being one of the most annoying, and it was not until the release of the Storm of Zehir that most of them were addressed.
These are all great games and, even if they series did not quite meet the expectations, I would recommend this Collection to any gamer. Completionists, however, should keep in mind that the collection is almost complete.
