The eSeries is a collection of Party AI Scripts for Baldur's Gate II: Shadows of Amn and the expansion, Throne of Bhaal. Currently there are seven scripts included in the series: eArcher, eFighter, eMage, eMulti, ePriest, ePureF, and eThief. As you should be able to tell from the names of the scripts, they are tailored to specific character classes. There is some overlap in abilities, but generally speaking, the scripts are most potent when they are assigned to a character of the corresponding class.
Note: The eSeries contains specific shout responses systems that allow the individual scripts to coordinate effectively, therefore it is not advised to mix the eSeries with other Player AI scripts.
"The eSeries sprang from the magnificent Player AI Scripts known as the gSeries, which was developed by Greg Hodgson (aka Sarkyn). The gSeries was fully fleshed for doing battle in Baldur's Gate II: Shadows of Amn but unfortunately for those of us who loved the capabilties of the series, Greg chose to exit the Baldur's Gate Scripting community prior to updating the scripts with the scripting options available in the final chapter of the Baldur's Gate Trilogy, The Throne of Bhaal. Considering the intrusions of real life and all the other wonderful videogames available for capturing our imaginations, I don't blame Greg in the slightest for finding other things to fill up his time. Wherever he is, I hope that life is treating him well. Cheers, Greg!
So one day while playing Throne of Bhaal, I decided I just couldn't take the gSeries' lack of ToB support any longer and although there were a couple of other high quality Player AI Scripts out there, Rich Martel's and Gebhard Blucher's for instance, my loyalty to the scripts that had performed so well in Shadows of Amn superceded my interest in convenience and despite my relatively rudimentary understanding of Infinity Engine AI scripting, I, with Greg's consent, jumped in and began to overhaul the gSeries to bring it up to ToB date."
