Lol, there are 4 different Neverwinter games, all made by different people.

Neverwinter Nights (AOL) - one of the first non-textbased (Visual) online games, closed despite popular demand.

Neverwinter Nights (Bioware) - essentially the Sword Coast moddable basic 3D game and online capable version of Baldur's Gate, with revolutionary modding abilities (favorite)

Neverwinter Nights 2 (Obsidian) - An up on graphics and gameplay, and campaign storyline, from the Bioware version, and otherwise a grow-revival of the game after Bioware stopped support of NWN.

Neverwinter (Cryptic Studios) - a fully online game with limited modding, better graphics, gameplay, and good storyline.
