Multiplayer

Multiplayer means having more than one human being playing in a module at the same time. This includes both Persistent worlds and smaller groups playing through other mods, including the original campaign or Mask of the Betrayer.

NWN Comparison
In NWN, multiplayer generally worked. Conversation dialogs operated in a multiplayer-friendly manner, and PCs could travel between zones independently without risk of crashing the server.

In NWN2, multiplayer is full of lose and fail unless both the module author and the server host take extreme care to set things up perfectly. The default cutscene-style conversations are obnoxious in multiplayer, forcing everyone except the talker to stand around watching. Missing campaign files on the client can crash the server, as can insufficient GPU power during map transitions. Why the server should care what a player's graphics chip does is a mystery that only Ao can answer.

3.5E Rules Comparison
PNP handles multiplayer quite well. NWN2 does not.
