Hey guys, I just got the PC version of Skyrim a few hours ago, and I want to know some mods that will drastically improve the civil war experience, thanks in advance!

At this point, no.

The Civil War is one of the most complex questlines in the game. Improving or overhauling it will take awhile.

The perfect civil war mod will be one that uncouples the civil war from the main quest. One can dream...
