A single player mod that adds single play to multiplayer with as many bug fixes as possible.
Age of Redemption Mod
This mod is specifically made for single player and is designed to add single player to multplayer with as many bug fixes as possible. What it does is adds creature respawn so you can keep fighting, improved party AI so you don't have to deal with Wilhem trying to continuously cast Awe on a skeleton - also players like Serena will automatically know how to use Shambling Hordes on dead enemies. Simple mod, but cool. This mod includes configuration options in a config.txt file so you can turn off and on creature respawn among other things.
