Here's a neat little (68k) mod I created in my spare time. Below is a cut and paste of the readme file. Eventually I'll get around to making an AOW mod where there are no rebel provinces, only faction-controlled provinces.

All Out War
by Kekvit Irae

Viking Invasion Required

This simple mod creates a new campaign to play with. The changes from the original game are as followed:

~The game starts at 1087 in the Early period.
~Each faction has only one province at the start.
~There are NO agents whatsoever in the game. Want peace with a warring faction? Eradicate them.
~Inns have been removed.
~All faction AI has been replaced to EXPANSIONIST and the various EXPANSIONIST variations, except for the Pope. Expect no mercy from previously tame factions.
