I've been working on a mod for SAI to produce large-scale dreadnought battles. The final result is the mod that I've uploaded. The Oceans of Gore mod adds a number of new ships to the game, both historical and ahistorical, as well as increasing base capacity to give the player plenty of room to house these new ships. The read-me goes into more detail about this mod. As a note: this mod is not intended to have a historical premise, and buffs the strength of both powers to an unhistorical level (maybe the Germans more so than the Allies). I've tested it a bit, and it seems to be working ok, though please let me know if there are any bugs. I've fixed a few already, but there may be more.
"I cannot feel that a man-of-war is a proper place for a Chaplain...it seems to me uncommon odd, and precious near to cant, to tell the ship's company of a man-of-war with loaded guns to love your enemy and turn the other cheek when the ship and every man jack aboard her is there to blow the enemy out of the water if he possibly can. Either the hands believe it, and then where is your discipline? Or they don't and then it seems to me to come hellfire close to mockery of holy things" Jack Aubrey
