Introduction
"Britannia-style" games consist of these general features:

• historical war games
• players direct the forces of more than one side/people/nation
• area movement
• historical victory points scored periodically throughout the game
• reinforcements received based on areas held
• simple, "to-hit" combat resolution

Ancient Conquest
Biblical
R.J. Hlavnicka; Excalibre; 1975
Every phenomenon of any size must have its precursors; perhaps that's what this game and the next are for the Britannia-style game.
Not area-, but hex-based with counters that contain combat and movement points. All of a player's nations are played together and can even combine in defense, thought not in attack. There is no economic mechanism, so no new pieces are received as a result of occupation, only scheduled reinforcements. times. Many of the point goals are for taking cities. There is no stacking except in cities. The only other way to score points is to destroy enemy combat factors.

Britannia
British isles from the Romans to the Normans
Lew Pulsipher; Gibson Games-1986?/Avalon Hill-1986/Welt der Spiele-1991; 3-5 (4 optimal)
Stephen Oppenheimer's book The Origins of the British gives evidence suggesting that although there were invasions by Angles and Jutes, the Saxon invasion described by St. Gildas (a writer who may have had an axe to grind) may never have occurred. Instead it looks, at least to Oppenheimer, like Germanic-speakers were in England long before the Romans were, and upon Roman departure they simply resume power. If this is correct, this game needs a significant variant to remove the Saxon invasion and replace it with a Saxon resurgence.

Chariot Lords
Near East from the earliest history up until about 500 BC.
Charles Vasey; Clash of Arms-1999
Some differences from the Britannia rules include the following: initial setup is free and counter by counter; order of nations within a turn is random; redeployment phase; mountains count as a double area for movement; leaders do not add to the movement rate; the basic movement rate is three; leaders affect two areas in a round; defender retreats first; maximum number of rounds of combat is fixed (two or three); growth is not based on number of areas owned; units may return from the dead if for each a unit is removed permanently; invaders need not double-stack to overrun; submission rules are generalized; submitted units are not allowed to move.

Vinci
Prehistoric to Medieval Europe Philippe Keyaerts; Eurogames/Descartes Deutschland-1999; 2-6
Europe is divided into vague and unnamed territories of different types: Agriculture I, Agriculture II, Forest, Mountain and miscellaneous. Some territories also have a port or mining abilities. Civilizations are represented by randomly drawn pairs of counters of various kinds: military, resource, miscellaneous which are drafted by each player. The player then takes a number of tokens based on the number of players and red numbers on the counters which basically fixes the civilization size for its life. Civilizations begin from an edge of the map and move into adjacent territories. There are no dice. Conquest requires a number of tokens depending on the number of defenders and variations caused by terrain and special abilities. When after a few turns the civilization size has dwindled one usually decides to let it "go into decline". This turn, it does not move by the player chooses a new civilization. "Decline" counters are placed on the existing territories leaving only one token each to still earn points. And so on. Normally one plays two, three or four civilizations during the course of a game.

Kings & Castles
Medieval Britain
Gary Dicken, Phillip Kendall and Steve Kendall; Ragnar Brothers-2000; 3-4
Game on England and her conquests for up to four by the inventors of History of the World. Sides are represented by individual kings and entirely decided by draft before play even begins. Kings vary by the amount of extra force they add and in their primary spheres of activity. Play itself is diceless (and thus reminiscent of Vinci), the core of the combat system being a rather strange and unique form of arithmetic. The active player's forces must defeat the inactive defenders by the minimum possible amount – pieces are rated at value 1, 2 or 3 – but then only the strongest of these invaders remains. The other unusual mechanism is that over the entire course only twenty-five percent of one's forces are guaranteed to be one's own. The rest are drawn from a bag and may be one's own, but are also often the forces of other players, rebellious indigenous groups or mercenaries usable with any of the above. (There are also three levels of fortification.) The need for a player to clear out his force pool for the next set of forces means often going through unusual gymnastics. For example, he may use other player forces to conquer rebels, then use rebels to conquer them back and finally use his own forces to conquer the rebels. The other unusual feature is that in a four-player game, each player has only six turns and only on half of them may he declare scoring (which occurs for all players). Just as in their previous game, the board is no board at all, but printed on a folded cloth.

Britannia, second edition
British isles from the Romans to the Normans
Lew Pulsipher; Fantasy Flight Games-2005; 3-5 (4 optimal)

BGG entry
"Myths of British Ancestry" by Stephen Oppenheimer is a fascinating article on the early peopling of Britain, mentioning for example that Germanic languages were probably spoken there much earlier than previously thought and also the Norwegian invasions of the isles prior to the Romans. Obviously this game needs a prequel.
