Ah the HRE.... This was my very best M2TW vanilla campaign.

I tried to make the name "real" so to speak. As we all know at 1080 in the campaign this name is a total misnomer. I began by taking hamburg, and the other German reb settlements, including Metz. Then i went to war with Northern Italy. At one point both Milan and Venice were allied against me. While this was going on i allied to both Poland and Hungary to keep that front from exploding. It was at about this time that the Danes attacked hamburg and Antwerp so i fought them off then invaded Denmark. This started a two front war. That lasted for about 10 turns after i broke both Venice and Milan. Denmark took another 5 turns after that.
Honestly the HRE early units are very generic Catholic units and tactics, however i find that they are the most powerful of the early Catholic variations and have everything you require with few weaknesses.
After i finished off Denmark, i hyper-grew my kingdom. Built economy, ect. Then the Pope called his Crusade against Jerusalem around turn 39 i think. I was the first on the bandwagon cuz he was PISSED at me for breaking 3 different Catholic factions so fast. I barely beat a Portuguese army to Jerusalem. After that i expanded to form the Outriemer of old, including Edessa. Mass recruitment of priests and merchants to make the region !!!MINE!!!
Then i was brought back to Europe by the Sicilians attacking Bologna (spelling?) Of course it was underdefened so it was lost, then exterminated. I immediately got two FM's and a HUGE force of mercs to take it back. Then i side-stepped the Pope and hit Naples. The Pope then keels over, and elections.
???????
RECESSION!!!! The French guy won by one vote, (damn the Portuguese). So i quickly crushed The Sicilians and sacked them both for vengeance. At this point i did not hit the Pope, cuz that would cause WAY too much crap unless i could obliterate him in one turn. Which was impossible. However i did take the Med Sea isles. Another short period of mass building. The Mongols show up in Russia, nothing too major.
Then comes France attacking Metz. While i managed to repel them it kicked off the biggest war i had fought in the campaign up to that point. This was about turn 62 or so. The French its turns out had !$#!@loads of fullstacks waiting to say hi to me. About this time the Frenchy Pope dies. I have about 1/3 of the Cardinals on the map so i win of course. So now the Pope is my bestest friend EVARZ!!!!!!!
The High HRE units are bland at best. Imperial knights, im sorry, SUCK! I cant use them for anything at all. I was still recruiting feudal knights and Teutons for most of my campaign. ALWAYS get Teutons, these are the very best of the HRE high units.
Anyways i was at War with France. The fighting was fierce especially around Rhiems for the first 25 turns of said war. That place changed hand like 10 times or so. French cav is demonic, i swear. At turn 5 or so the the Death hits. Lots of dieing for 6 turns or so. I lost at least one army completely. After it was over i gained the upper hand against France, around turn 96 i finally took Paris. BRUTALITY for all the crap they put me through. Taking Paris destroyed the French, for while they still sent full stacks at me they were full stacks of crap. I take Caen from the English and am at eternal war with them for awhile, but nothing happens there. I get to Toulouse and is in the hands of the Spanish. Around turn 106 i crush The French and make peace, trade, then alliance with them. Scotland disappears soon after. Then i attack Spain. The Iberians must have fought themselves to death cuz there werent a lot of stack in any of the iberians nations. Spain and then Portugal fell fast. The Moors were a different story. I had to kill 2 Sultans to get them outta Spain. But after they were shoved out i made peace with them.
Then a period of mass building occurs. The new territories are brought up to scratch fast. The only real prob is Corduba. Not being my culture and so far from cap i have several rebellions there. As a huge Moor city i cant do nothing about it. Then the Americas open up. By this time i have all of the Cardinals and elections are at my disposal. I invaded Brazil first the Cuba and NA. It took me a while to find the entrance to the Aztec lands. and i underestimated them as well. First army to land got rolled under by 5 fullstacks. It took me twenty turns to finish off the Aztecs. i killed all of their FMs before the walls of Tenochtitlan and took that settlement as a rebel one. At this point i was about 3 territories from victory. i took two ME settlement and then to finish it all off, ROME!!!!!! All in all it was a fun campaign.
The late unit were bland as well except for the Zwihanders. Those guys are FUN!!!
