The current version is v1.4.23

Assassinations mod is a quest add-on for Baldur's Gate 2. Assassinations offers players an opportunity to explore the darker side of the PC's nature--to follow more fully in Bhaal's footsteps. Your potential targets vary from a corrupt priest to a Harper agent; you will meet members of the Council of Six and denizens of the gutter alike. You may show mercy or loyalty, engage in betrayal, double-cross and be double-crossed, stand trial, or get away clean.
The current version is v2

This is a mini-mod for all BG1 games: "vanilla" BG1 (with or without the add-on Tales of the Sword Coast), BG1Tutu v4, EasyTutu, and BGT. It adds several small quests and encounters to the game, including the "slime quest", jastey's former stand alone BG1 mini quest mod. The duration of the game time added by this mod is approximately 30 to 60 minutes, depending on playing style.
The current version is v3

Similar to its BG2 cousin, BG1 Unfinished Business ("BG1UB") is designed to restore many of the cut items, quests, dialog, and encounters from the game's final release, as well as try to tie up some of the "loose ends."
The current version is v6

This mod adds 525 items, 450 creatures, 275 spells, 160 areas, 15 new areas, 25 stores, 24 quests, 11 new creatures, 6 new songs, 1 new NPC, 1 new city, and 1 movie. This version also includes Candlekeep Chores and Candlekeep Chores Fast Forward.
The current version is v1.9

There are four chores that must be completed each day. At the end of the day, if you've completed the chores, of course there's a nice reward for you.
The current version is v2.1

If you don't want to mess with Bhaalspawn's childhood - install this, speak with Gorion and ask him to "paddle your ass like he means it" (This is only available to neutral or evil alignments with a non- heroic reputation) . It should work at almost any point along the days of chores, so long as they are not done for the day. The rest should be pretty straightforward.
The current version is v1.1

Classic Adventures will be a compilation of many of the old and some new classic PnP (Pen and Paper) modules. There are several newer mods that will also be included into this project just for some variety.
The current version is v0.49

Adds new encounters, improves the druid grove, makes the Shagbag encounter slightly harder. As usual, Encounters should be compatible with most other WeiDu-based mods, and should be installed after all official patches and preferably the Baldurdash Fixpack. Encounters requires the Throne of Bhaal expansion pack.
The current version is v1.01

This was originally a partial conversion for BG1 - Tales of the Sword Coast. It now uses the WeiDU format, and is a part of the BG Trilogy. New spells, items, 5 major quests, new areas, and 7 new NPCs are available to your party. Most NPCs have quests. Quests include rescuing a child from vampires, saving a town from a dragon, and searching for missing people.
The current version is v2.05a

A mini-mod that adds new items and encounters throughout the game.
The current version is v2.6

The Quest Pack contains a number of components designed to add additional adventures throughout Baldur's Gate II: Shadows of Amn and Throne of Bhaal. While the expansion is supported by some material, it is not required. ToB-specific components will be automatically skipped if ToB is not detected. Some components may expand on existing quests, while others may be completely new. All are independent, optional to install, and do not rely on one another technically or in terms of story.
The current version is v2.3

Dungeon Crawl is a new quest mod add-on based on the popular Web comic Dungeon Crawl, Inc. and written with the permission and cooperation of comic author Nathan Sheaffer.
The current version is v3

Adds a selection of small diversions and side quests. None of the components included in this mod will interfere directly with the original game's main plot and all quests are optional. Some of the quests were inspired by the various "Iron Modder" competition themes at the Pocket Plane Group.
The current version is v3

Have a thief? Just started a new game or are you still putzing about in Jonny's dungeon or the Promenade? Then do yourself and your thief a favor and download and install the Expanded Thief Stronghold 'mod' for BG2. It expands upon the thief stronghold & stronghold quests quite a bit and, hopefully, makes it a lot more fun and interesting.
The current version is v2.14

Fading Promises introduces Aidan, a fallen paladin of Amaunator, who has a couple problems. One of them is that he's dead. Another is that he never completed his last quest. You can't help him with the first, but he would be very grateful for your assistance with the second. Who knows? You might even give him the courage to face the judgment he has so long avoided.
The current version is v1

Fishing for Trouble is a new quest mod by resident area creation guru Yovaneth, and centres around five completely new major areas throughout the Baldur's Gate II world.

The current version is v0

To initiate the quest, go look and speak to the whores in the Copper Coronet. Expect some fourth-wall breakage and some outright silliness, and keep your eyes open—you may even spot someone you know.
The current version is v5

Tactical challenges and improved battles, new quests and encounters, new types of monsters, fixes and tweaks, item randomizer program, new item upgrades, a new Ranger kit, a new druid kit, and a new fighter kit.
