It's the expansion route it allows and encourages them to take, on very sketchy historical grounds, and how that messes with the formation of two world powers, one of which quite clearly played an important role in their demise in real history.
Once again, it has to be admitted before providing additional comments, that the event was not seen as a game-changing, world-breaking one, until reading the posts in this thread. After
@Travis_Bickle's ardent claims, the author started to seriously question the plausibility of the crimean throne being handled to the ottos, in the
universum of eu4.
The claim has a point in regards to the rather interesting relationship between the house of osman and the house of giray, and how simplistically it is depicted in eu4. That is, they are represented only as a simple march due to the event, which is immediately revoked to a vassal status at the hands of the code. The code never keeps a vassal, whether they are useful or not; it only annexes them.
Naturally neighbouring the ottos causes a sudden danger, and accelerates the inevitable death of lithuania. Again, the author has already
expressed own suspicion on the event having drastic regional effects, let alone global effects. After this thread, it was decided to go and test with yet another run in continental europe. Of course, as the sample size is only one, the observations cannot be extrapolated for a general view. The case example is used only to provide the perspective of the author, how the thread's claim is agreeable to a certain extent (or rather,
understandable), and how the doubt of the author is reasoned.
1456: The event fires as early as possible, sigh. As an unrelated info, the player is lübeck; not-so-aggressive play, but decided to go for the unsafe path -no austria alliance.
1456: Only nine days passed, and the code-ottos revoked march status of crimea to vassal.
- In this case, the author agrees, that this situation is unacceptably rapid.
- For the player, it is favourable, as the lithuanians already tried their chances on conquering riga; and yet they were beaten even with a lübeck trade league of below-average size (only 8). It does not matter if the ottos are closer or not; the lithuania tag is already vulnerable. The reason of this will be given later before the conclusion part of this post.
1486: Lithuania mauled muscovy a bit; surprisingly poland did not invade wallachia (another poisonous behaviour observed after the austria patch). But by this time the ottos is close to annex crimea, and they are already in the process of annihilating genoa in the region.
- The conquest of genoese holdings in crimea, as early as this case, is plausible from a historical perspective. Needless to say, in eu4, the shadow kingdom event, and the incompetence of the code-emperor (austria) is the main catalyst.
1499: Lithuania trashed the great horde, harassed muscovy; but its impending doom has started. Like clockwork, the ottos declared on lithuania. Not shown in the image is, france is the catholic defender of the faith (naturally, sigh), and will be beaten badly.
- Again, the author agrees to the claim that annexation of crimea accelerates the downfall of lithuania.
- The author still doubts as this is the main cause. Explanation will be provided later, as mentioned before.
- Referring to author's own claims: The moronic code decides to stay allied, and only to AQ; code-ottos' previous allies were tunis and karaman. Tunis fell for some unknown reason; karaman was eaten by the ottos (and ramazan-mamluks) in an ally-war.
1507: After the lithuanian war, ottos target serbia. Note that in the previous war, they only conquered former great horde lands, and lower don from lithuania. Not clearly visible, but at the same time, denmark declared on lithuania for the baltic lands. Muscovy is having a bad time.
- Getting closer to the point of the author; but before, it has to be mentioned that, denmark starts this war as it has already conquered livonian order; fine. But after integrating norway, they go berserk. Integration of titles is outrageously simplistic; in the case of denmark-norway, it is inevitable.
- Still, lithuania's demise will not come by this danish invasion.
1554: Remember muscovy having a bad time? Not exactly. When the code denmark is able to swallow both norway and sweden, then it is highly possible to see a muscovy-free map. But the player is lübeck; this means denmark will fall; natural result is muscovy forming russia, and its first target is lithuania. Tsardom strikes back; lithuania is out.
1556: An unrelated but brief pause to support the author's own claim: The ottos at the hands of the imbecile code take admin, and quantity (sigh), after an influence opener. The code takes the influence only for the idiotic reason of annexation bonus, whereas the influence for a player is beneficial only,
and only, for two tags: When playing austria, or any hre emperor tag (the other one is ashikaga-or japan opm daimyo legion run). Yet, the code decides to take it as ottos, and has no vassals, as if that would make any difference. Utterly unnecessary, incredibly deranged.
- What is the result of this?, one may ask.
1561: The result is mamluks declaring on the ottos. At this point ottos already wasted all their economy, manpower, monarch points on the unnecessary wars in ruthenia; mamluks surpassed them by a factor of 2,5. Mamluks vassalise ramazan, annex them, and declare on the ottos.
- This is nothing, of course. Ottos, even at the hands of a brain-dead code, armed with an alliance ring of anizah, yas, AQ, tunis; loaded with influence, admin, quantity; with half of potential manpower; are still able to obliterate mamluks, as it will be in this case.
Coming to the point:
- The author agrees that the crimean event is oversimplified, and is not reflective of the actual events between the ottos and the crimean khanate.
- It is still not convincing to see this event as the main reason for the lithuania's fall. Judging by the observations, the main reason is another event: Successor of wladyslaw the third, as it was in this example.
- Yes, before everything else, poland chose not to form a personal union with lithuania, therefore leaving the ruthenian plains vulnerable to all: denmark, muscovy-russia, in most cases bohemia, in few cases austria-hungary (the code is also mostly incompetent to form that), and naturally, the ottos. In one extreme case, the author observed a wallachian turbo-kingdom over entire ukraine (such occurrences happen more frequently when one plays in americas or indonesia).
- Commonwealth is a fickle one, as it may or may not survive into the late game; but when poland and lithuania do not form the union, the catastrophe is certain. Needless to say, when the player is brandenburg-prussia, whether poland or commonwealth, it has to go in order to play.
In conclusion, it is agreed that the crimean event is highly problematic, and it belongs to the list of eu4
universum's oversimplifications
. It is agreed that it accelerates the ottos' expansion in the region, but not causes it, as the ottos already claim caffa from genoa, then proceed routinely into crimea, if the event does not grant them march crimea.
It certainly does not matter for the ottos if the event is scrapped altogether (bad design choice), or improved as a disaster-chain (too much work, but the author refrains from giving any suggestions), as the ottos, whether at the hands of the brainless code, or a novice player, is the most powerful tag at the start no matter what happens to them, if not the luckiest (castille), or the easiest (austria), or the largest (ming), or the trickiest (portugal), or the mightiest (ulm

).
It is still not convincing to see it as the main reason for the collapse of poland and lithuania tags, as they are bringing their own doom onto themselves, and the other neighbouring tags are causing equal damage, if not more than the crimean event.
Fun final note: Mzab died within the first four months into the game; poor lads, tunis usually gets an estate-mission right from the start; the last patch hit them really hard
