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.
YMMV: Legend of the Five Rings
Idiot Ball: Why, in the name of all that is holy, would the most vehemently anti-Shadowlands Clan in Rokugan ever ally themselves with the Shadowlands during the Clan War? Ask Hida Kisada, who apparently thought it was a good idea, and paid for it dearly... like pretty much anyone else in the Clan should have been able to tell him.
Memetic Badass: Hida Kisada claims this trope for the Crab Clan. Yoritomo of the Mantis and Moto Chagatai of the Unicorn have reached Chuck Norris-level badassery in some circles.
Designated Villain: This is the Scorpion Clan's job. The first Emperor Hantei asked the Scorpion to be the bad guys that the other clans can fight against in order to insure that the clans never unite against the Empire.
God-Mode Sue: With the possible exception of the Spider/Shadowlands (and then, almost entirely limited to Daigotsu himself), the Scorpion wildly fluctuate between this and the Anti-Sue. Examples of the former include such ridiculously over the top moments as leading a political revolt against Toturi III, previously a Chess Master without equal, that was done with so great an ease that it occurred mostly off-camera and without explanation, while examples of the latter include the entire clan holding the Villain Ball against the Crab so tightly that an entire army walks right through both clans' territories without either the wiser, allowing the Spider to infiltrate Rokugan unopposed. A common player complaint is that Scorpion victory is either a certainty, regardless of who actually won, or it's doomed to fail, even if the Scorpion actually won the storyline tournament. Other clans are subject to this, too, but it's been outright stated by the story team that the Scorpion have to do both to an extent to appear plausible at all.
Magnificent Bastard: The Scorpion Clan specializes in this trope, but there are plenty to be found among the other clans, as well.
Including at least one Scorpion-trained Emperor (Toturi III), and current Emerald Champion, Shosuro Jimen.
Even Evil Has Loved Ones: Daigotsu Kampeki, the Spider Clan Champion and one of the most dangerous men in the Empire, nonetheless genuinely cares for his wife.
What an Idiot: "Okay, I know that every other guy who has invoked the powers of darkness to get an advantage has brought only ruin... But I know that I can do better."
Rokugan in General
Broken Base: Well it goes without saying that the supporters for each of the factions (even ones no longer active in the game) are pretty passionate and will defend their faction with great zeal. One can even find intense debates and divides within a single clan (the Shinjo vs. Moto flame wars among the Unicorn player base have been going strong for over a decade) to say nothing over the debates about which CCG ruleset was best, First Edition vs. Third Edition RPG, CCG vs RPG (judging just from this page), etc. etc. etc...
Canon Sue: Iuchiban. For others, Daigotsu. Kaneka was also accused of being this during the Diamond/Lotus Era.
The Monkey catch a lot of flak of this sort, too, as they're a minor clan started by a peasant who claimed samurai status, have a very potent bushi school, haven't really had much happen to them in the timeline, and have the patronage of the Scorpion Clan.
When Hida O-Ushi's uncle Tsume scornfully asked her (formerly Unicorn) husband Hida Yasamura whether he would have the resolve to cut O-Ushi down if she was slain and raised as a zombie. Yasamura replied that it would be impossible for him- because if O-Ushi was slain, he would already be dead.
Of all people, Hida Kisada had two: one, when realizing his son Hida Sukune, whom he had sacrificed to Fu Leng, had returned as a sacred spirit AND forgiven Kisada. Later, after Kisada's own resurrection, he found a previously unknown heir, a Dragon with less concern with battle than with law, and showed the boy favor anyway — proving that even Kisada can change.
The Interspecies Romance between Daini and Mara is a subtle one, but it's really quite sweet — and very significant, when one remembers that these two had to overcome serious obstacles, including very alien appearances in each other's eyes, completely different racial psychologies, and his own culture's traditions of arranged marriages, stoicism and opposing of romantic love. Yet, despite it all, they managed to fall in genuine love and marry because of that love. "Legacy of the Naga" even has a throwaway line about how Daini is perfectly comfortable allowing Mara to assume her true, tail-slithering form as opposed to needing her to be in her bipedal form, and even enjoys her coiling embrace.
Shoju Bayushi's wife, Kachiko, once asked, revealed to him that she'd been having an affair with Hoturi Doji, and that Shoju wasn't their son's father. After a tense moment, the boy was brought in, with Kachiko expecting Shoju to kill him. Instead, the maimed Scorpion picked the child up, declared him his heir, and said that, as the child of the woman he loved, he would care for the boy like his own.
Dork Age: What many people consider The Hidden Emperor Arc to be.
Some people throw Diamond and Lotus Editions onto that pile.
It's pretty uncommon to find someone who liked the Destroyer War, as the Spider were the only clan that came off as even slightly competent. Subsequent developments (the Spider becoming a legitimate Great Clan, Fu Leng taking over Jigoku and joining forces with Daigotsu to save the Empire, taint only affecting the willing) have been similarly poorly-recieved.
And the third edition of the RPG had pretty terrible proof reading, including an appendix in Emerald Empire with NPCs with Honor stats sometimes twice as high as the rules allowed and a revision of a rather important rule in the Revised core rulebook that made the Defense skill unintelligable.
Fanon Discontinuity: As far as many older players are concerned (especially those who play the RPG), the canon storyline ended with the Second Day of Thunder and Toturi I becoming Emperor.
The Destroyer War, Daigotsu taking over Jigoku and making the taint voluntary, and forcing Iweko to make Spider a Great Clan is being treated as discontinuity as well.
Tear Jerker: Hoturi dying in Kachiko's arms after defeating Fu Leng in the Second Day of Thunder. While she forgives him for killing her son (and though he did not know at the time his son too) during the Scorpion clan Coup and they reaffirm their love for each other.
And then later, to permanently bind Shosuro to the lake beneath Kyuden Bayushi, Kachiko drowns herself in its waters knowing full well that her soul is likely to be bound and she won't be able to move on to the Heavens. Her last sight before going under is Hoturi, newly resurrected, reaching the side of the lake.
Kachiko inspires many of these. During the coup, Hoturi proudly kills Bayushi Dairu, the heir to the Scorpion leadership. It isn't until years later, as Hoturi's pondering Kachiko's sudden and passionate hatred for him after years of saying little to one another, that Hoturi realized the truth: Dairu wasn't Shoju's son, but Hoturi's.
That One Disadvantage: Momoku. You can't spend Void Points. Imagine if you couldn't spend Willpower in The World of Darkness and you have an idea of how utterly this will screw you. Worth ten Character Points (the most of any disadvantage); not even remotely a fair deal.
It's now only worth 8 points, and only prevents you from using the common Void Point expenditures. You can still use Void Points to activate Techniques that require them.
Dark Fate. When the GM feels like it, you will betray everything your character holds dear, most likely including the other players, and probably become an NPC, if not dead (or a Fate Worse than Death).
They Just Didn't Care: More or less Wizards of the Coast's attitude during the entire period where they had joint rights to the game along with AEG. They day that AEG bought exclusive rights back from them was a day of great rejoicing. Though some critics also say that this is the attitude towards Japanese and Samurai Culture of the post Wick Story Team as the setting has drifted further away from that over time.
