Okay here's a quick starter's help for England... (5.7)
-turn 1: move princess over to France and get marryage alliance with france, before that let her ask for trade rights, move the diplomat towards the german regions, towards central italy, move the caen army into the castle, get the caen general on the ship and move him into london, that will make him a governor and you need money first, same with the general in the nottingham region, off to london he goes, don't develop nottingham or caen yet, use the movement points of the king and the relocationg generals to build some towers in the london region, move the english merchant from the caen region towards the silver near frankfurt, move both cogs into the harbor in caen and disband one, move the spy from nottingham towards london, move the cardinal immidiatly northwards and denouce the heretic in the nottingham region, build a scholarium in london
-turn2: flemish princess approaches caen and asks for trade rights, say yes and also marry her to your faction heir, flanders becomes your ally, you will get a mission, if the mission is "take rebel settlement Southhampton" forget it, if the mission is "get trade rights with germany for 2500" great, lets's do that, give the ancillary for london to your faction heir, don't move your generals yet, as it's winter, move the cardinal towards london, move the diplomat towards central italy target is the pope, grab the garrison of caen and move it on the ship, then drop it off in the london region, leave behind one units of peasants
-turn3 move the king on the ship and let him garrison caen, the second prince moves into the nottingham region, builds towers to keep the rebel spawn away and then garrisons nottingham castle, diplomat should be near rome now, depending on missions either talk to german/venice/milan first or go straight for rome, cardinal ships over to the mainland and begins moving towards narbonne, merchant should be on a silver in Frankfurt by now and will start generating good money, get all the soldiers into london, get the spy on the mainland so you can start spying for governors points, you will need at least ten points to build markets
-turn4 continue with above strategy, it's winter again and not much else is doable
-turn5 a new prince comes of age, immidiatly board him and get him to london for education, take as much army as you can from london and move it to nottingham, build towers, contact the pope, give him trade rights, gift him military access, gift him map info, ally with him, check the crusade targets and your papal standing but don't ask for a crusade yet
-turn6 winter again, if you have the diplomat missions you are lucky, else just put your diplomat next to venice and wait for the siciliany princess that comes sooner or later, this can save you a trip down to nalpes, you can either give every faction there trade rights immidiatly and move on with the diplomat (brings standing, trade and gov points), or wait for the mission that gives 2500 (only good if the mission comes immidiatly, else the diplomat costs too much), amry should have arrived in nottingham by now and should be spear militia + peasant archers
-turn7 grab the prince from nottingham + army, sail the ship from caen harbor next to nottingham, put the army on the ship, sail around the northern rebel fort and besiege the town north to nottingham, build 2 rams, 4 ladders, you must conquer that town in the next turn so your castle/city ratio is 50/50 again and you can start making money, begin to spy in the mainland so your gov points increase, it#s your choice if you just go for 20 gov points at first or if you go to the max, try to concentrate on 95% targets like merchants, diplomats and princesses, only spying on other factions gives you points, rebels don't give you points, if you can afford it recruit the one unit of welsh longbowmen for the assault on edinburgh, sail the ship back to caen harbor so the rebels don't get it
-turn8 take edinburgh and occupy it, leave behind 4 units of spears, disband the welsh longbows if you are short on cash, put the rest of the army back on the ship (which comes back from caen harbor), and drop it into the nottingham region , if possible put it into the castle, sail the ship back to caen, check your papal standing again
-turn9 ask for a crusade on narbonne, if narbonne is not in the list take an other rebel target (damascus, malta whatever, as long as it's the rebels), move the army from nottingham towards london
-turn10 the pope asks you to join the crusade for 2500 bucks, great let's do that, faction heir joins the crusade with the army which came back from nottingham, now you have 2500 bucks, access to crusader sergeants and crusader knights and a crusade against the rebels, that's all you need to clear out the huge rebel stack in the southhampton region, once this huge stack is gone (it's mostly longbowmen so the crusader knights will kill them), move the army but not the heir on the ship, sail over to caen and let your king take leadership of that army, recruit the crusader sergeants and knights from the caen region and sail back the fresh crusaders to london while the king goes off to the crusade target (hopefully narbonne) with the battered army, merge the battered troops and refill the ranks with mercs, the heir can take over the fresh troops, fill up with militia and mercs and kill the rebel stack in the london region, after killing those rebels move inside london and disband the crusading forces (one by one so you get the maximum "used military size")
-turnx try to get the crusade target with the king, possible if it is narbonne, if it is damascus just forget about it, the king is too old to reach it, rather move inside caen and disband the troops and wait out the crusade
From there on you can start developing your regions and forces, take southhampton once the council offers 10.000, blockade bremen for a while, should be easy from there on, reinforce caen first, get the fort in caen but don't touch the fort in Angers or else the french will besiege it and attack you even before the first dark age, not very good, try to grab caernarvon before the irish take it, but that's kinda hard, try to get dumfries, take out the forts there and station troops at the northern border, once caen and the north is secure finally take the forts in london and southhampton/nottingham, deveop to your liking from there on...
And ready my hints thread
