* AlternateHistory: An inevitable outcome, considering the premise. Ever wondered how it'd look like if the Danelaw managed to successfully resist Anglo-Saxon reconquest and carve out a permanent domain in Great Britain, unswayed by indigenous powers or the Norse kings across the North Sea? Or if the Norse-Gaelic Kingdom of the Isles (Sudreyar) had annexed the Scots instead of the other way around? How about the British Isles being entirely ruled by an Irish confederacy under King Flann Sinna?

* NoPronunciationGuide: Not in the game itself, but the punny achievement for beating the campaign as Mide, 'Mide Your Own Business', relies on 'Mide' being pronunced similarly to 'Mind', when it's actually more like 'mee-yeh'.

* AnAxeToGrind: This being practically the Golden Age of Viking conquests, these kinds of weapons ''dominate'' the battlefield, being found in all factions but especially prominent in the Viking kingdoms. They are used in both one-handed and two-handed varieties.

* TheBerserker: A highly elite unit available to the Viking factions, fearsome Warriors who simply excel at butchering other infantry in droves. Unlike how they are usually portrayed, these Berserkers are both well-armed and well-armored, wielding swords and shields (as opposed to the typical [[AnAxeToGrind axes]] or [[{{BFS}} large swords]]) and very disciplined. They do still possess a berserk mechanic, however, which grants them increased melee stats the longer they remain in melee combat.

* TheLowMiddleAges: The entire time period of ''Thrones of Britannia'' is set in the late 9th century British Isles where Vikings have begun to later settle and clash after periods of raidings on Saxon and Irish settlements.

** Since the game begins after the battle of Edington, the whole nature of Est Engle and Westseaxe's relationship is presented incorrectly. In-game, the two begin as intense rivals, just a hair's breadth from war. In reality, after his defeat at Alfred's hands at Edington, Guthrum converted to Christianity and changed his name to Aethelstan, with Alfred as his ''godfather'', and Est Engle became a half-ally, half-vassal of Westseaxe until it was finally annexed somewhat peacefully by Alfred's son Edward in 918. [[note]]The game ran with the notion that Guthrum treated Edington as a mere setback, and his supposed conversion to Christianity was an act to make Alfred lower his guard. Historically, while Aethelstan kept the peace between the two factions, there was no evidence on how seriously he regarded his conversion.[[/note]]

** Although it's downplayed in the game itself, this is what is happening to Guthrum's Kingdom of Est Engle. The Danes living there soon started to adopt the language and culture of the English already living there. Even Guthrum himself has converted to Christianity by the time of the game's start, and changed his name to Aethelstan (although the game does not reflect this and calls him Guthrum [[note]]In a fan Q&A session ahead of release, game director Jack Lusted explained that this was simply for the sake of player familiarity with the Danish name[[/note]]).

* BadassBeard: Inevitable, given the setting.

* UnfortunateNames: There's a province named after the earthwork called Offa's Dyke. ''No'', it gets worse - the game spells it as Offa's Dic.

''Thrones of Britannia: A Total War Saga'' is a standalone game in the ''VideoGame/TotalWar'' series that serves as a sort of indirect sequel to both the classic ''VideoGame/MedievalTotalWar'' ExpansionPack ''Viking Invasion'' and ''VideoGame/TotalWarAttila'' ExpansionPack ''Rise of Charlemagne'', taking place in the early Middle Ages in the isles of Britannia. As the petty kingdoms of the Anglo-Saxons, Gaels, Welsh, and now-settled Norse continue to squabble, kings famed in story and song begin to rise and build legacies that will outlast their line; there can only be one ruler of Britannia, and each intends his children to hold that throne. However, further raids from the mainland arrive all the while, and there's no guarantee that another power might not look upon the fractured isles with the intent to conquer...

* FightingIrish: Ireland is host to many clans and kingdoms, Mide being the playable one, and whose bickering had been the source pf their weakness as the Norse began to expand along the island's eastern shores. Due to their bonuses to monasteries, which provide them with income and research, it also crosses with ReligiousBruiser and BadassBookworm.

* ISurrenderSuckers: Implied with the game's depiction of Guthrum, who can renege on the treaty signed after Edington, and re-ignite war between Wessex and Est Anglia.

** Although it's downplayed in the game itself, this is what is happening to Guthrum's Kingdom of Est Engle. The Danes living there soon started to adopt the language and culture of the English already living there. Even Guthrum himself has converted to Christianity by the time of the game's start, and changed his name to Aethelstan (although the game does not reflect this and calls him Guthrum).

** '''Public Order''': Unlike many other games in the series, Public Order in ''Britannia'' is a resource, as commodity extraction industries decrease public order, along with some buildings. If public order gets too low, rebels will spawn in the province. Public Order is increased by buildings in the province capital (main settlement).

* ArtisticLicenseHistory: While generally less prevalent in this title compared to others in the series, a few inaccuracies have been noted - some of which are deliberate to add more interesting features to the time period, such as Ragnar Lodbrok being treated as a historical figure, siege equipment being more advanced than ladders, and the Picts of Circenn making heavy use of crossbows instead of primarily for hunting.

* AwesomeButImpractical: The Community Civic tech branch is this to factions who do not start near Ireland or Scotland. In order to access the branch, the faction must capture a Monastery provincial capital, which is only found in those two locations.
** The Fame victory conditions are the only victory conditions (out of three possible choices) which cannot be completed with the help of vassals. In addition, it is very likely that a vassal or ally is holding a monument you need as part of a Fame victory.

* EasilyConqueredWorld: Only provincial capitals are fortified and have garrisons. It is possible for a small raiding party to infiltrate a realm and wreck havoc on its economy by occupying settlements.

** The Great Viking Army (Northymbre and East Engle) have to track both their Legitimacy and Heroism, which represents the favor of their Anglo-Saxon subjects and Norse warriors respectively. [[CultureClash Raising one often can result in lowering the other.]]
** Viking Sea Kings (Dyflin and Sudreyar) can conduct expeditions and focus on raiding.
** Welsh Kingdoms (Gwined and Strat Clut) are dealing with the [[WeAreStrugglingTogether squabbles]] between the two brother-kings after the death of their father. Also, Heroism mechanic encouraging battles and conquests in order to gain bonuses.
** Gaelic Kingdoms (Mide and Circenn) have the Legitimacy mechanic, which holding cultural lands or defending fellow Gaelic culture can allow diplomatic bonuses with their fellow Gaelic kingdoms.
