These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
And with Rajas of India, we have an entirely new continent, new cultures, new Indian events and a potential for the early establishment of Hindustan. What does the fandom care about? The new Messalian heresy, which has incest and the worship of Lucifer as a god figure. To wit.
And to complete the trifecta, the most loved addition of Way of Life is not the new Focus system, nor the addition of new events specifically for roleplayers, but the ability for any character to seduce their sister.
Sunset Invasion, a not-entirely-serious DLC focused on an Alternate History where the Aztecs invade Europe. Some loathe the concept, some like the idea of western Europe having an equivalent of the Mongols, others appreciate it as a potential countermeasure against the Moors, and some are content to buy the DLC and just deactivate it for certain campaigns.
It also happens with the some of the more recent Portraits DLC. The artist changed, and a big part of the community thinks the art comes off in poorer quality than before. Some people (keeping up with the recent fad in the forums of making petitions for everything) are petitioning the mods to redo the facepacks. The issue often descends into a Flame War.
The current trend of DLC expansions has players divided on how Paradox is treating previously implemented content, and if favorites are being played. The Old Gods was one such example, as discussion of favoritism being given towards the Norse due to the far greater degree of content and lack of pre-patch balance, with other pagan religions showing a far thinner amount of content. Critics have also argued the lack of post-expansion attention to various mechanics, despite players demanding attention, such asthe Decadence system that was implemented with the Sword of Islam expansion.
Rajas of India breaks the base even further. The patch containing free content disrupted multiplayer capabilities, while the expansion of the map to include India meant that lower end computers who could play the game previously now struggle to do so, and Paradox's attempt to compress portraits to free up memory resulted in bugged portraits. These problems persisted for over three months after ROI's release.
Charlemagne continues the base breaking tradition. Several features in the DLC itself didn't work as planned, while the patch containing free content introduced new bugs. In addition, the fanbase is divided over the inclusion of "Zunist" pagans. It's either a fun exploration of a fascinating pre-Islamic faith in Afghanistan, or overly obscure add-on that no-one asked for, ignoring fan interest in adding content to existing religions and heresies such as Hellenismnote which would have been just barely hanging on in the Mani peninsula in 769 or Yazidism.
Ending Fatigue: It's entirely possible for a player who knows what they're doing to achieve their goals — up to and including World Conquest — well before the game ends. The rest of the game then becomes about protecting what you've already gained from being conquered or breaking under its own weight, which is usually not quite as compelling as the initial goal.
Goddamned Bats: The Old Gods adds raiders who will plunder your territory, then flee back onto their longboats before your army can get to them.
The Karlings largely owe their status as The Scrappy to being this in the 867 start. They aren't necessarily a threat, but they take up huge swathes of Europe and are very difficult to dislodge.
Good Bad Bugs: The demo for the sequel restricted play to only four characters. However, almost imminently players found out they could play whichever character they wanted by picking a character from the demo list, then quickly clicking on a province on the map before the game loads - and play as the ruler of said province.
They also found out that the demo doesn't end twenty years later but specifically in 1086 and that if you set the start date at 0AD you could get 1086 years of playtime out of the demo. However, this screws up the triggers.
The Scrappy: The Karling dynastynote the descendants of Charlemagne in The Old Gods 867 start, who start with the powerful and prosperous kingdoms of East and West Francia,note Later known as Germany and France, respectively Italy, and Lotharingia (among others) within their realm. Due to the way alliance and title mechanics work in the game, they often hold onto their thrones much longer than they historically did, and any attempt to unseat one of them (or half the wars they get involved in at all, really) ends up dragging literally half of Europe into the fray. Charlemagne didn't improve matters, as certain deaths can result in a Karling blob of either the Empire of Francia or a Holy Roman Empirethat includes France.
Adventurers, introduced in the Old Gods DLC, randomly lets characters gather a host to assault a realm they have a claim on, or which follows a heathen religion. Adventurers automatically scale with the realm they assault no matter how little sense that would make, making it perfectly possible for a pre-christianised Finland to produce a 50,000 man army out of nowhere to attack your Frankish Empire or for one of your courtiers to go adventurer and form a 20,000 man expedition to take your kingdom... from inside your own capital. Worse yet is that adventurers are treated as non-rebellious and saddle you with tyranny, dishonourable or kinslayer penalties for dealing with them (clearly, arresting your son-in-law for openly declaring the overthrow of your realm from inside your own court is the mark of a tyrant) and leave you at the mercy of the RNG.note Although giving them land prevents them from invading you. Removing the diplomatic assassinate option just made this mechanic even more annoying.
The tribal transition to feudalism or republicanism is a real thorn in the side of pagan players. Reforming a tribe into a more advanced form of government is expensive and time-consuming at the best of times, but pagans can't reform their government without first reforming their faith. The AI almost never does this on its own. This means that pagan players have to conquer essentially an empire-sized realm first, since it's impossible to reform pagan religions without controlling at least three holy sites. Pagans by design have great difficulty holding a large realm together, and given that the realm is militarily gutted immediately after the transition, it leaves the fledgling kingdom defenseless before surrounding states who would ''really'' like to get back at you for a few decades of continual raiding — which, incidentally, is the only way tribal states can support their economy.
Gavelkind inheritance. For the uninitiated, this inheritance law means that your senior heir gets the current ruler's primary title and capital holding on succession, while they compete with their brothers and / or sisters (depending on gender inheritance laws) to parcel out the remainder amongst themselves. Despite gavelkind being present from the earliest versions of the game, no one has managed to work out what sort of logic the game uses to parcel out the titles, which typically happens in such a way as to ensure very fragmented, disjointed, and aesthetically unappealing territorial splits. While it's moderately effective at keeping AI realms split, most players hate it for the chaotic results it produces and try to switch to something else at the first available opportunity.
Surprisingly Improved Sequel: The original game, while it had its fans, was definitely a flawed game, with a Troubled Production and quite a lot of bugs. Crusader Kings II, on the other hand, has received by far the smoothest launch of any Paradox game to date, and received almost universal acclaim from the fans. Expansions like Sword of Islam, Legacy of Rome and The Old Gods have only served to make it even better.
