Hooked Gamers has written up a review of Neverwinter Nights 2, giving the RPG sequel an overall score of 9/10.
Beyond its triumph as a game, Neverwinter Nights 2 also represents a triumph to two companies Atari and Obsidian. Atari and Obsidian have a somewhat checkered past from past games they have published and developed. The Temple of Elemental Evil, a turn-based Dungeons & Dragons RPG, was released in an unfinished format with many quests broken due to the removal of certain elements from the game. As the publisher, Atari was somewhat to blame (as was the now-defunct Troika). Obsidian suffered from a similar problem with Knights of the Old Republic 2. While overall it was a very strong offering, the entire game broke down into an ending that felt rushed and incomplete. Together, there was some speculation as to whether Atari and Obsidian could pull off a complete game. As you have read, I believe Neverwinter Nights 2 to be a masterpiece in my mind, both companies have proved themselves to me. I fervently hope to see an expansion in the near future.
