Just to get back to you all, I'll post a 60 turn campaign diary to let you know how I did.
On the note of Scotland; they took every settlement other than Exeter and Galway, they even took Dublin!. However, I had to dramatically reduce each settle Garrison to about 5 units and one general for Scotland to not loose to Rebels. Exeter was taken by Leon & Castile, they love that town, but have done nothing since. Scotland is happy with it's Spanish neighbour and looks like it is fielding an army to attack Galway (speculation). Moreover, I have noticed that due to the large number of settlements Scotland now owns, it is very spread out and if I genuinely wanted to recapture the isle, it doesn't look difficult, no major garrisons other than Edinburgh. I had given them a large military boost to.
Here's the diary, nothing really surprising (long list warning! lol):
Edit: non = nothing of note
the symbols are there to help me identify key events.
This is not an attempt at an AAR or anything Roleplay wise, just random notes taken of important events.
Set up: SS 6.3, VH/VH, Meneths Compendium; Savage AI, Istanbul mod, Longer Assimilation, 2 TPY.
Initial territory; Acre
Starting Florins; 10.000
Kings Purse; 3000
Army: one major army consisting of; 3x Crusader Knights (4 vet), 5x Pilgrims (1 Vet), 2x Dismounted Crusader Knights (4 vet), 3 x Mercenary Crossbowmen (1 Vet), 3x Generals (1 vet), 4x Crusader Sergeants (3 vet).
I now know that the Army is too strong, too many generals and money wasn't an issue (first ten turns were in debt however). Either way, hope this helps anyone trying to improve England's difficulty, I found it a fun campaign (so far) but a little bit easy so I'm going to tinker about and see if by giving them a territory in each part of the map will make things more difficult; I.e. Caen and Acre or Acre and London (regards to whoever suggested starting area of Caen). Also the two Crusades made a huge difference, so excommunication (Xanthippus of Sparta) would make it a lot harder.
Thanks everyone
