You when it turns out he ended up in Anatolia and ends up uniting mankind only to be worshiped as a God-Emperor:
Or rather, as Sigmar.
Seriously, the next DLC could be a DLC dealing with the enhancement of religion, the expansion of the barons' role (that is, making more events to make county-life much more interesting and challenging), just a little bit of TRADE...
...and a bit of naval combat. Not determinant, just a bit. More related to transportation and resources than actual combat. Something like:
- An army marching through a coast province with a navy following it (with the navy having the "support army" option, which costs you money, but your troops get stronger morale and (maybe) reinforcements.
- A fleet can "provide resources" somehow to help oversees territories.
- Fleets, as it happens, were usually merchant ships rearranged to carry soldiers, and naval battles were not battles between ships, but more like land battles on wooden castles. That means you need soldiers there, and the soldiers you're transporting also count.
- Also, if trade is in, raising your fleet would make your trade rates suffer. Instead, you could purchase galleys, which are serious warships that don't "go away", like mainland
retinues, but are expensive to build, and you might need an extra building (an Arsenal, or a Shipyard) to be able to build galleys.
- This way, you can provide help to Crusader kingdoms oversees, making their troops stronger, and also simulate a well planned attack supported with a fleet into enemy land.

Here I'm mirroring the French Crusade against Aragon, in which the king's army crossed the Pyrinees while a French fleet set out to provide support and supplies through the coast. The French lost the war when the Aragonese fleer defeated the French fleet in the Battle of the Formigues Isles. Without its supplies, the French army succumbed to disease, famine and loss of morale while besieging Girona, and ultimately retreated after some weeks.
I'll tell the end of the story, because it's cool: the King of Aragon watched them pass through the Pyrinees into France, with the King of France being deadly sick, and then some Aragonese soldier shouted "Shame on you!" to the king of Aragon, because he was letting the hated French escape. He thought of the agreement he made with the king of France, but then he though "Err, screw it", and attacked the fleeing French army, utterly crushing it.
Just to show how important lines of supply were at the time. Some people will say "but this is not really a war game", but I beg to disagree, since in war is where characters shine or darken the most, and this game is about characters. Mind, the king of France died shortly after this war, and his son, who was there as well, got a very unpleasant view of his neighbours to the south. He was not really going to be a friend of Aragon. This shaped his character, while rising others like Roger de Llúria, the Sicilian admiral that won the sea battle for Aragon, to stardom. He's still one of the most memorable characters from Aragonese history to this day.
