The NWNSERVER.EXE is the multiplayer aspect of Neverwinter Nights, the Aurora Engine's co-op aspect of NWN.As soon as CDPR releases WITCHERSERVER.EXE , we will have co-op play.Yes, you can make modules designed for co-op and multiple players in the Toolset.No, you can't play them cooperatively until WITCHERSERVER.EXE is released by CDPR.Best answer I can give you, as a 6-year veteran of NWN online play. 
With your experience in the NWN realm, do you think that persistent online mods will become available for The Witcher?

The tools to maintain and host a persistent world are far less the issue than good module design, dedicated people making it work, solid quests for when moderators are not online, and solid moderator Adventure-Maker staff to keep things interesting while people are logged in and having fun. Ad-Hoc adventure-making staff will make or break a good persistent world. Scripts alone do not make a good game! It needs heart, and the people behind the game are that heart.Our answer to your question is "Yes', but the answer involves people, not tools or programs.
The Aurora engine is multiplayer at heart. Mind you, we know CD Projekt have heavily rewritten it, but have they taken that functionality out? I'm away from home this week and can't check, so could someone else have a look around the script libraries?dibujante said:
According to what we've found, there's no reason why the multiplayer aspects were taken out. We've dug pretty deep into Djinni. But as Paul mentioned, there needs to be a server executable for it to function and connect into the client. As of yet, there is no server at least in The Witcher or Djinni at all, merely the client networking architecture.That being said, the possibility is there. It's a matter of the server being created.
I believe he was speaking about the "team tactics" aspect of multiplayer... what happens when two or more combos are used on YOU? or, if your combos are messed up all the time by your own guys?That does need worked out maybe, but that's farther down the road once the MP aspects are activated and implemented... as is all things, it will be a work in progress...I once heard that "we reserve the right to get better".
