Neverwinter Nights lends itself well to a variety of different play styles. The following are a few of the more common ones. * Persistent world - Where the game server is "always on" and players come and go at will. * Single-player - Game client and server run on the same computer. Only one player and no DM. * VPnP - Small-group, session-based play. Usually a single party with a single DM. * Arena - Party vs. party combat in one area with two bases.
