Someone had to do it, right? Here are the best mods I've found for Icewind Dale, to help you enhance your experience. These are listed in best order of installation except where noted.

1) Widescreen Mod
Sharper graphics on moderns LCDs. No additional GUI mod is needed, as IWD was designed with a more scalable interface than most other Infinity Engine releases.

2) Unfinished Business for Icewind Dale
Restores and finishes content cut from the original release, hence it blends with the original game perfectly. Stable, fun & professional.

3) Item Upgrade for Icewind Dale
Adds the ability to upgrade your equipment. Definitely fun for crafters!

4) Icewind Dale Fix Pack
NEW! This is split out from the Tweak Pack, which seems to no longer be available. Below are the notes for the old Tweak Pack, but it looks like this new Fix Pack just contains fixes only. I will update this post if I find a replacement for the tweak components.

Adds bugfixes, minor cosmetic tweaks, cheats, ruleset tweaks.
I recommend the following components:

Assorted Fixes:
Everything.

Cosmetic Changes:
Weapon Animation tweaks (less repetitive sword swinging animations)
Restore IWD Loading Screens (HIGHLY subjective. Most people won't care, but I prefer the original look of the pre-Trials of the Luremaster loading screens)
Icon Improvements (replaces some icons with their usually more detailed BG1, BG2 equivalents. Subjective, but subtle enough many won't even notice)
Force All Dialog to Pause (no more cheap shots from enemies attacking while are you chatting)

Content Changes:
Personal Preference. If in doubt, skip.

Rule Changes:
Also very subjective. Some make the game closer to Pen and Paper and many are outright cheats. If in doubt, skip.

Convenience Tweaks and/or Cheats:
Higher HP on Level Up (may be worth it to first-timers. Ensures you don't get poor die rolls with IWD's random HP on level up system, which is based on a roll of the character's hit die)


Optional:
Auril's Bane
Adds new items, spells, a quest, new creatures, new AI scripts and more. Can modify the feel of the game a bit, so I recommend holding off for a first-time playthrough. Works best if installed before the tweak pack. Overall very fun and high quality mod.

Icewind Dale NPCs
Don't want to make your own party? Check out these premade, chattering NPCs. Not ideal for tacticians and powergamers, perhaps, but if you want a bigger dose of roleplaying in IWD, this mod will make you happy. Best installed before Tweak Pack.

Full Plate & Packing Steel
Changes the AD&D 2e Armor rules so that light armors give you a better chance to dodge and heavy armors absorb damage. This is as opposed to heavy armors decreasing the chance you get hit.

Yes, D&D armor rules are strange. The most common justification I've heard for it is heavy armors gives you more "glancing blows" which don't do damage.

Opinions aside I haven't actually tested this last one, being accustomed to standard D&D rules. It may be interesting to try though. I'm also pretty sure this should be installed before the tweak pack, as usual. Be careful to note compatibility as some tweak pack components directly conflict.



As mentioned by chautemoc, there are a couple sites keeping comprehensive indexes of mods.

Sorcerer's Palace Modlist

Does Icewind Dale require a GUI mod like Baldur's Gate and Planescape?

Widrescreen mod works just fine...any chance to get it work on multyplayer? I had an old version of this game and when yesterday we restarted to play it crashes everytime I press load game in tcp\ip mode, we played on windows 7 32bit, now we have 64bit is that the problem? Any chance to get it working? (tryed x3 sp3 and vista sp2 compatibility but same problem...)

p.s. I can provide Italian text translation full functioning^^ No, I setted it on 1920x1080 and no problems like the others two game you mentioned^^


Edit: Ok I got it working xD

if anyone have the same problem of multyplayer crashes just flag the option of "use 3d hardware acceleration" in the config menu, and everything runs just fine xD

I would like to thank all the staff for bringing here this awsome game, as I said before me and a friend of mine restarted to play this just yesterday, and we coudn't play becouse of this error :( thank you so much ^^

Only the Improved BAMs mod seems to be particularly useful though (for nicer inventory graphics).

Added, thanks for the reminder!

I'm not sure what difference there is between the Tweak Packs's improved icons and "Improved BAMs". Anyone know? I have only installed the former.

Oh sorry, I didn't know it included them. I'm sure it's fine then. This mod uses the icons from BG2, while the Tweaks pack uses BG2, IWD2 and BG1 icons -- so that's probably better.
Thanks for updating. :)

Do you recommend installing all components of the Tweak pack?

I mentioned the components in the Tweak Pack I really like and recommend for anybody. A whole bunch of them are outright cheats or modify the rules a lot, so I tend to shy away.

Besides the tweaks I mentioned though, I only install Restore IWD Heart of Winter Loading Screens. The ruleset tweaks do look interesting though, so I may give them a shot next playthrough.

A note on the widescreen mod..unlike Planescape Torment, I do recommend 1280x800 here for 16:10 users.

I've replayed IWD a few months ago with the widescreen mod in 1920 x 1080 and it worked just fine, screenshot below.

Yes it works fine, I just find it way too tiny (1680x1050). With Planescape it doesn't seem as tiny, or at least doesn't feel that way.

Can always keep it small but play in a window. I do that with BGT.

Anyone know if there is a program similar to the BiG World Project that works for Icewind Dale?

There is IWDTutu and it implements IWD 1 in the IWD 2 engine. That also means it updates the game for 3rd Edition D&D, which is a HUGE change!

Existing mods won't work for it, but once it comes out of beta we might see some conversions. That said, getting out of beta may take a long while, yet! Development seems to have stalled.

It's not quite what you were looking for, but it's a step in that direction. We may never see anything actually analogous to The Big World though.

Anybody know where the mods from gibberlings 3 might be located, now that it appears that that site is down? Hopefully only because of overload from the releases here, but down nonetheless. If nobody knows a site that hosts the mods, maybe someone who has them would be willing to upload them somewhere?

Gibberlings 3 is up - I just checked.
