All Vassal Challenge

[Ramses II CP]

Yeah, on VH campaign difficulty your reputation is going to go through the floor in a hurry. Might be best to try it on H/VH. It'll still decline, but it'll be manageable.

I'm thinking you almost have to go catholic here and possibly one of the Italian factions, for that fast access to the Popester. Move fast, ink alliances in one direction and make war in the other, then return provinces to the enemy to boost relations sufficient to make them accept vassalage. One thing you will need is a good economy to pay for keeping your relations on an even keel.

When you're ready to go after the ones you allied with at the start find a pretext for war (Like excommunication) and go to town.

France would probably be a good one for this style again, as you could go get England and Scotland fairly quickly, then work through Iberia. Could be a problem keeping Milan/Venice/Hungary from getting eliminated though.

I'm pretty busy at the moment, but I'll given this a try eventually.
