Thinking of picking up NWN 2 soon because I'm having a D&D craving that can't be sated irl, so a friend and I wanna do the co-op because I remember seeing that the game had it, but after doing some research I'm slightly confused on whether or not we can. All I do know is that we need our own copies.

So mainly questions are: Is multiplayer still possible? And is it easy to set up?

You'll both need your own CD-key.

However, the game comes with a "default" CD key in the installer, and your own personalized CD key is attached to your account. While the default key is pretty much banned everywhere, if you're just running a private LAN game that won't affect you and one person can use the default key while one uses the personalized key. Yes, multiplayer is still possible. The official servers are long dead, but that won't affect you if you're using LAN or doing direct connect. There are fan-run server listings if you want to go over the internet, though if it's just the two of you direct connect should suffice.

We don't wanna worry about servers, it's just gonna be 1 friend and I. As for LAN or direct connect, are we gonna have to do a hamachi kinda thing?

Awesome, thanks for the help!
