After having GREAT fun with BGT (still chewing on the very last battle I consider giving the "Big Picture" a try. But can anybody tell me or direct me to a site which lists what mods it incorporates and what it changes?
I'd like to know
+ what are the new areas?
+ what are the new quests?
+ what is improved or changed?
+ will I have to install every mod and then merge them with BP or does BP install all of them itself?
.
Keep in mind that I know NOTHING of the other mods except for BGT and Ascension (which seems to be woven into BGT). So I don't know any of the imporvements/changes of SOS or TDD for example.

Check out Weimer.

Under each mod lists what new changes are added into the game. But I warn you, I don't consider installing TDD as it is extremely bugged.
