''Sengoku'' is a RealTimeStrategy FourX game created and published in 2011 by ParadoxInteractive.

The player assumes the role of a Japanese clan leader during the [[JidaiGeki warring states period]], with the starting date being either right after the start of the Ōnin War of 1467, or UsefulNotes/OdaNobunaga's rise to clan leadership at 1551. Similarly to ''VideoGame/CrusaderKings'', Sengoku focuses on individual characters rather than abstract governments, and finding wives for your sons, producing heirs and pleasing your lord or vassals is as important as conquering lands and constructing buildings. It is not uncommon to see a so-far successful clan tearing itself apart because of a succession crisis, and if your clan leader dies without a direct male heir, it's game over.

In addition to the standard currency (which is used to construct certain buildings and hire soldiers for a leader's retinue), each character has a certain amount of honor. Honor can be gained by donating money to the emperor, granting titles to your vassals and through certain character traits. In turn, honor is spent by hatching plots, declaring wars and other “shameful” tasks. If a character's honor gets too low, his liege might order him to commit seppuku, so [[AccidentalAesop maintaining your honor is sometimes even more important than being rich or powerful]].

While the game shies away from historical [[EventFlag Event flags]], some historical events like the Ikkō-ikki rebellions or the Portuguese and Dutch landing in Japan are bound to happen in every game. Other then that, the game itself is basically a large sandbox with an overarching mission to control 50% of Japan, then convince the emperor to grant you the title of Shogun.

Not to be confused with [[SengokuRance any]] [[Anime/SengokuOtome of]] [[VideoGame/SengokuBasara these]] [[VideoGame/SengokuSNK games]], or [[Manga/SengokuYouko this]] manga. Can be seen as a SpiritualLicensee to {{Koei}}'s ''Taikou Risshiden'' series.

!!This game provide examples of the following tropes:
* AChildShallLeadThem: Possible if a clan leader dies before his heir turns sixteen. This is especially dangerous since vassals are less likely to follow an underage leader and he can lose control of the clan in favor of a pretender.
* AlternateHistory: You are only changing Japan's history and in a very limited sense – no matter what you do, [[InSpiteOfANail it will still be ruled by an emperor and behind the west in terms of technology]].
* ApatheticCitizens: Averted. Even if your feudal vassals are pleased you can still suffer through religious or Ikkō-ikki rebellions.
* ArrangedMarriage: Finding wives for your sons and sending off daughters to ensure political favor is a big part of this game's diplomacy.
* AWinnerIsYou: Once the player controls 50% of Japan, petitions the Emperor and keeps the peace for three years, the game pretty much just pop a message saying "Well, congratulations, Japan is at peace and you won the game. Um, you can quit now if you feel like it".
* BalkanizeMe: It is possible to convince minor vassals from a rival clan to join your clan or rebel against their own clan leader.
* BigScrewedUpFamily: Be ruthless in your conquest, fruitful in the bedchamber and generous to your cousins and you'll most likely end up with half of your lands being ruled by uncles and other relatives. Of course, intermarriage and rebellions are usually soon to follow.
* CharacterPortrait: Each character above the age of sixteen gets one.
* ChokepointGeography: Terrain and province layouts grant certain bonuses for armies who attack or defend them, and patch 1.2 added the impassable mountains mod.
* CivilWar: Once a clan gets large enough it is almost impossible to stop these from happening.
* CosmeticallyDifferentSides: Gameplay is almost identical no matter which dynasty you choose to play. The only difference is whether you choose a clan leader (in which case you have to fight other clans) or a minor ruler (in which case you're usually more concerned about plotting to form your own clan).
* ColorCodedArmies: All clans use the same color-swapped Samurai figure to represent their armies.
* CurbStompBattle: Newly-formed clans will sometimes form with only three or four provinces and quickly fall pray to the larger bordering clans.
* DeadlyDecadentCourt: On top of this, each landed character has his own court, and therefore, the ability to hire ninja and ronin. That is potentially a ''lot'' of deadly decadence.
* EasyCommunication: Even in Feudal Japan, the player knows about everything that happens in his domain the second it happens.
* EverythingsBetterWithSamurai: The standard soldiers of the Japanese clans.
* FogOfWar: Strangely for a strategy game – averted. You can see everything that goes on in all of Japan at all times.
* GameBreakingBug: The AI seems deathly afraid of risking his honor, meaning it is almost impossible to convince other leaders to join your plot or break away from their clans.
* HeirClubForMen: Producing male heirs is one of the most important aspects of gameplay.
* HistoricalDomainCharacter: All characters present at the game's start are actual historical leaders of their respective Japanese clans. As of patch 1.2, a new starting date was added to the game, set right after OdaNobunaga assumes leadership over clan Oda.
* [[HiredGuns Hired Swords]]: The player can hire Ronin to serve in his own personal retinue.
* IHaveYourWife: Two-way and contractual in most cases, but ninja can be hired to play this trope straight.
* HonorBeforeReason: There are ''game mechanics'' for this.
* InfantImmortality: Oh so averted. ANY character can die, including newborns and minors. If you're feeling extra evil you can also order Ninjas to assassinate a character, regardless of their age.
* InTheBlood: Characters pass on traits to their descendants.
* InstantAwesomeJustAddNinja: Ninjas can be hired to preform various stealthy actions, from burning down a guild house to weakening defenses and assassinating characters.
* JapaneseChristian: Westerners make an appearance around the mid sixteenth century, bringing Christianity (and [[CoolGun Arquebuses!]]) with them.
* LoadsAndLoadsOfCharacters: An integral part of the game.
* MagikarpPower: Unlike other Paradox titles, there are no claim, casus belli, core or culture mechanisms so even the smallest of clans can become a giant monster clan in a couple of decades.
* {{Ninja}}: Notable in this game for being wandering clans who will work for exactly one year and then move on.
* PutOnABus: The player can force underlings to retire to a monastery
* RealTimeWithPause: Just like all other Paradox strategy titles.
* RelationshipValues: Each character has an opinion of your character. Keeping these high is the only way to ensure the loyalty of your underlings.
* RiskStyleMap: In proud Paradox tradition.
* {{Ronin}}: Goes with the whole warring clans business.
* {{Samurai}}: Naturally
* TheStarscream: Goes with the whole samurai and clan business, to the point where there's whole game mechanics dedicated to dealing with such individuals or being one yourself.
* SuccessionCrisis: Managed to conquer a third of Japan? Your clan leader has five daughters and a six year old boy with a lisp? Good luck trying to hold your lands!
* TheEmperor: While the emperor himself is not a playable character, the player can petition him for titles or donate to the imperial court to gain honor.
* VideoGameCrueltyPotential: Oh so very much. If your honor is high enough you can declare wars on whomever you like, send ninjas to assassinate a rival's single male heir, revoke titles and banish to monasteries.
* VideoGameGeography: For some reason the northern Japanese island of Hokkaido is missing from the game. Japan also seems to float in the middle of the ocean as both Korea and China are not present on the game's map.
** This was done to keep the game focused on conquering Japan, not expanding elsewhere. Hokkaido in particular was omitted because Japan didn't begin colonizing it until late in the game's timeframe, so it seemed like an unnecessary mechanic for one area.
* WeHaveReserves: Since armies are mostly made out of levies, it is sometimes useful to send them to their death, disband whomever was left alive, wait a couple of weeks and raise them again at full strength. The base manpower for levies never decreases so you can never get to a point where levies stop regenerating, as would normally be the case in other Paradox strategy games. There is also no visible "manpower" number for standing armies (retinues), like in other Paradox strategy games, so in theory nobody can ever run out of professional soldiers as long as they have the gold to pay for recruiting and upkeep.
