i can see what you posted there and it's not true! like that song "undewear" from Royal republic....
@ProkyBrambora I dont know where you started, but dont mess with HRE when its already existing in your game. It's better to chew smaller kingdoms at east at first, only then to start chew away from HRE. HRE is not OP anymore, but you have to be skilled to know ways how to get on their lvl (money=>mercs, allies, holy warriors, vassal holy warriors etc..., like that i usually fight against 2-3 times bigger opponent)
!!!!!! make byzantium your ally!!!! if they will allow
dont know what is your religion, but if you are slavic, be sure you are head of religion (you will get some help and you can hire holy warriors for free)
dont mess with HRE
if you are catholic and messing with HRE, be sure you have allies and mercs. For mercs, you need enough money.
if you start from oldest date, prevent creating HRE. I did it, and right now I have Bohemian Empire from Balt to Croatia, from Meissen to HellKnowsWhere. Franks should bother me much more, but it's some time to get back to CKII...
Incredible, better to pay attention to your politics
