I've read through the "Ultimate Link list" up at the top of the forum but I'm still not entirely clear on what to I want to be grabbing just yet.

For Neverwinter 1, I have the CCP, CEP, CTP, CMP, NWNCQ, and a couple of other .HAKs that make the game just a little bit more pretty.

I'm looking for the same thing with NWN2, so here's what I've been looking at so far:

Kaedrin's PrC Pack

Trees Textures Overhaul
Complete NWN2 textures
Sharpened Textures

All of NeilMc's Texture mods

.....and the NWN2 client extender.

I have no idea if the PrC pack plays nicely with all of those. I'm not sure if any of those mods make the in-game characters look prettier either. There are other mods like:

Tony K's Companion and Monster AI 1.1
Chainsaw XIV's Complete Craftsman
Heed's PC Tools
.....and United Colors that caught my eye.

Do all of these mess up my ability to connect to multiplayer servers? Can anyone give some suggestions for different packs/mods? I'm also not really in the market for campaign modules at the moment. I'm generally looking for stuff that either brings the game into the modern age of HD graphics, or things that increase the level of realism and actions my character can participate in.

For NWN2 I would definitely suggest the Facelift pack. It is only a cosmetic modification, but the PC head models are very well crafted. They are only available for a handful of races though, but nevertheless it is still a very good mod if you are looking for ways to upgrade the look of NWN2. I think the version uplodaded on NWN2 Nexus also has new tiefling head models which have not been added to the NWN Vault version.

I am not familiar with how mods would influence your multiplayer experience as I have never played NWN2 online myself, but I would assume that any modification that alters the original contents of the software would cause problems in a multiplayer game where people have different or no mods installed, but someone with personal experience will probably give you advice on that.

In addition to my above post, is there anything beyond the Facelift pack that spruces up the character visuals?
