CP pretty much covered things. There's also all the "reforged" weapon models, Barb's heads, creature overrides, Zeks patch haks and the big one NWNCQ. I also use a first person camera mod so I can explorer in first person (with
dungeon roofs on).
There's also nwnshader that gives you some of the more modern effects. The guy who worked on it was involved with the MW modding scene too. There's two versions Bahamut_0214 and Chronepsis 0.2.2.3 - the later is a bit buggy so i've been using v2.1.4 for a long time. It's a little bit of an acquired taste but it can make things look nice most of the time. Here's a
screenie I took just now of a old save from the Endless Nights 3 module. I'll admit it's dated but it looks
ok and tbh there's so much content and so much D&D in the game that the game play is usually pretty good. My only real gripe is a lack of fine party control, this is most noticeable with spell casters.
Oh yeah, I always play with Old Mans Beard's henchmen mod. Lets you build your own party in any module
and carry them over from one module to the next.
In case you couldn't tell… It's one of my all time fav's.
NWN2 looks quite a bit
prettier out of the
box and can also be modded to be even more so (the gawd awful weapon models and faces are a good start) and you can use things like sweetFX or ReshadeMe with it easily. But as PB says there's something a little off with the camera and it feels sort of confined during play. The MQ is also long and a bit tedious tbh, I'm yet to finish it. But you do have 100% control over your party and there is lots of content for it too, even a BG remake and I think rjshea is building the NWN1 HoTU campaign in NWN2 so there's that to look forward to.
Head over the NWNVault for all the mods you could ask for.
You can pick both titles up for a couple of dollars these days and they are my go to games if I feel like D&D.
Have fun
