Nevermore87: Is it possible to edit/create game content like races/classes/feats/spells? If it is, which tools do I need to use?
NWN comes with the Aurora Toolset aka 'nwtoolset.exe' found in your NWN install folder and also can be launched from the NWN main program menu as 'Toolset'.
The scripting language that NWN uses is a subset of C language - so there are LOTS of reference material out there and quite a bit of it custom made for use with NWN. As noted there are even tools like 'Lilac Soul Script Generator' which can create basic scripts. You'll find a wealth of material (scripts, modules, haks, guides and more) in places like
neverwinternights.info
and
neverwintervault.org
...
To the poster who had trouble with viewing scripts in MS Word - MS Word can mangle programs (code, script, source code) and is not meant to be used as a scripting tool - so this may have inhibited your success. I know the scripts in the OC on all the creatures and objects are functional and not at all worthless, so I wonder if your viewing via MS Word may have skewed your opinion?
You can totally change stuff within the OC - pretty much anything is open to editing here (save only some game-internal functions like 'pick pocket', most anything can be scripted in NWN. I've spent the last 14 years buliding a NWN module - we have scripted systems for many things not possible in the OC; swimming, flying, climbing, jumping, squeezing through tight spaces, custom spells [many from D&D like Wish, Liveoak, Blink and more].
NWN is an AWESOME game engine and very prone to being modified. Come see what we've done, we can "talk shop" if you like.
