blaknwite: 1. I keep hearing that the best part of these games was/is the player modules? Where do I get this? Is it still around?
2. I assume these "modules" are like D&D modules, so like adventures? If that's the case, can I make my own?
3. Is it possible to play this locally with my friends or do I need fancy dedicated servers? i.e. Is it easy to host a server?
4. I heard there were persistent worlds back in the day. Are any of these still around?
1. Yes, you've gotten the link to the current main source. Keep in mind that they can be wildly, wildly different and unique.
2, yes and yes.
3, locally is fine, only potential problem is port forwarding or DMZ.
4, yes, install NWNCX and most will be listed automatically.
blaknwite: Have you made any modules? Are they very difficult to create?
I have, the main two public releases are
Siege of the Heavens and
A Peremptory Summons.
"Unfortunately," I only got into NWN modding in the last, oh, 5-6 years and spent the first few years learning how to build/code in the first place -- so those modules were only released in the last year or two and thus they didn't get enough votes to get into the Hall of Fame before we had to migrate all the original content from the original vault. How do you know that you should believe me? Well, the mini-review on the Siege of the Heavens page is by RogueKnight...who made the Hall of Fame series Swordflight. So if he thought my stuff was good, then it probably is.
My point is not "MY STUFF IS AWESOME AND YOU SHOULD PLAY IT!" -- in fact, the modules I made are very different from "standard" D&Dish adventures and will highly appeal to some people while not being interesting at all to others. Rather, my point is that the Hall of Fame list is hardly exhaustive -- especially for content that's come out in the last few years. I happen to know that RogueKnight is working on the third part of Swordflight, for example, but I'm not even sure how it'll be "inducted" into the Hall of Fame list (if at all) on the new vault. So it's still worth poking your head around and asking for advice on overlooked modules.
Difficulty wise, well, it depends on what you want to do. My modules feature heavily involved boss fights that go far, far beyond the typical "Hey it's a boss with lots of HP" encounters that you usually find and require advanced and complicated scripting. In fact, I'd be surprised if more than, oh, half a dozen to a dozen builders in the NWN community could replicate what I did. But you certainly don't *need* that advanced scripting to make an engaging and interesting module -- I simply happen to be more interested in combat design than most. And wanted to see how far I could push the NWN toolset.
If you want, think of your question as asking "Is it hard to make a paper airplane?" Strictly speaking, it's extremely easy to make a simple paper airplane that's perfectly functional...but you can create something amazing with more effort.
