The Viking Age Scenario


Aug 13, 2002
Calgary, Canada
This is a Scenario for the Dark and Medieval Ages in Northwest Europe. It goes from 500 AD to 1235 AD.

Within the scenario folders, there are 4 different maps... one of each for Quick, Standard, Epic and Marathon. When you enter mods, select the map under Additional Maps (Viking Age Quick/Standard/Epic/Marathon) and click on scenario after selecting the map. You can then choose which civilization to play.

Most of the scenario is complete and playable. The tech tree has been adjusted quite a bit and 5 techs have been added. There are numerous buildings and units added as well.

I need to do a bit more artwork. I will likely have to adjust the text entries over time to suit the Medieval theme... I have made a lot of text changes but there are likely a lot more anachronisms.

I will be adding a few more buildings and tinkering with various items in the scenario as time goes by... mostly to do with balance as I receive player feedback. As well, I will enhance the scenario as time goes by to get the AI to act appropriately and less predictably.


Requires BNW and DLCs... esp the one with Denmark. I have not tried playing with only the one DLC.
EUI okay... but some Scenario Top Panel items will not work correctly. As well, technolgies need to be selected directly from the tree by double-clicking on the tech icon on the top left of the top panel.
DLL mods have been unsuccessful. The religion elements get messed up.

Important... some code elements rely on city and unit names. Do not change the names of Earl units/Archbishop or of Cities with Archbishoprics or Earldoms in them... or of London.

I have a lot of information to add in the next while. For now, I'll just upload a dropbox download link and a copy of the map in PDF format.

There are some new concepts I have introduced. A number of civs have subkingdoms with which they obtain very positive diplomacy numbers and bonuses. At some point, many of these subkingdoms amalgamate with the civilization in question upon the acquisition of either Nobility or Chivalry techs. Additionally, there are many scripted actions on behalf of AI civilizations that allow for a bit more historical accuracy. This mostly has to do with historical Viking attacks... the point being that for now, even given a peace treaty, the Viking civs are not to be trusted. I am going to work on refining these scripted events as time goes on to make them seem more rational and random at the same time.

During the course of creating this scenario, I used a variety of resources provided by members of this site plus many of my own creation. I have lost track of many of the creators however, because of computer wipes and interruptions in work. Because of this, I would ask that if anyone sees their own work, they let me know so I can properly credit it in the mod description and in the thread. I will list some that I do recall below (I will collect spelling of names as I return to this thread over time):


wHoward - longship, assistance with much code. probably etc.
Machiavelli - his unit promotion code, building created code, unit created code, assistance with code creation, probably etc.
Gedemon - city state's UU code
Don Quixote - Ingame Editor for testing, assistance with code creation
Iceco - not another city state's mod code elements
R8XFT - Some leader portraits from his mod/some unit and building/unit graphics
JFD - Norway map/TopPanel stuff/some HRE ideas
FramedArchitecture - lua from his National Park mod
LeeS - code assistance
Neirai the Forgiven, TPangolin - code and improvement from "Colonialist Legacies - The Wabanaki"
Morlark - Smarter Tech Tree Pipes code
KyteM - Dynamic Cultural Overview UI Enhancement
? - Standing Stones Mod code
? - many unit graphics
Leugi - ProductionPopUp lua to handle UI to show Unique Missionary
LastSword - Missionary Override lua for Unique Missionary

I likely missed some... let me know if that's the case.
Uploaded the newest version, 7. Tinkered with several traits to increase balance. Replaced Trelleborg Building with Trelleborg Improvement for Kingdom of Denmark. Replaced Bondi Unit with Vik Improvement for Jarldom of Hladir.

Will improve the original posts to be more informative over time. As of now, have listed all items for only Denmark... others will come over time.

If anyone is playing this scenario, I would appreciate any feedback you may offer. If you do, I would suggest playing either quick or standard speeds at first, as the game will feel very long otherwise.

Cool map. I tried twice playing as Wessex and the game crashed about turn 15. Perhaps I will try again as another civilization
I played as Wessex for 50 turns on a Quick map just last night. I had no CTDs occur. Not certain what happened to cause the crash listed 2 posts above.

If anyone experiences similar crashes, I'd be grateful to know the circumstances.

One thing is, as noted, mods may cause conflicts with the scenario. As well, the maps are set at certain difficulties and game lengths. So if you change the difficulty of a map from the game menus, differences with the map settings may cause a crash... similarly, the game length set by the particular map should be accepted as is.

In future, I hope to make this scenario into a DLC in which scenario length and difficulty will be independent of the map... and only on map will be needed rather than one for each difficulty that I use now.
I am having better luck this time. After getting through 50 turns as Sweden just fine, I went back to Wessex and am now at turn 120 without crashing. So, maybe it was a one-time thing where the AI was making some move that made the game crash, and in a different setup it didn't happen (the great Marbozir said that happens sometimes).

Anyhow, without the crashes, I am free to focus on the issue of survival, as Normandy, the Britons, and what's left of Mercia all took advantage of the Danes' attack on me to attack at all corners of my kingdom. I'm playing on Immortal, which is at the end of my abilities, and will keep you posted. It's definitely a fun scenario.
Version 8 of the Scenario is uploaded to Dropbox.

The second and third posts have had much more information added as to traits and uniques.

Many changes have been made. Artwork is vastly expanded. Worked on the text descriptions... there are still more to do. Refined the Uniques of the various civilizations... in some cases, quite a bit. Changed some civilizations traits (especially Normandy).

Refined the idea of Cultural Units. These are "levy" type units that are cultural in nature... for example, the Irish have Ceithern and Kerns, while the Scottish civilizations have Clansmen. The Carolingians have Franscisa units. Usually, these will be limited in number in relation to the Barracks a civilization has constructed. They normally do not count towards maintenance and number of units and do not require iron (it is assumed they are provided under feudal obligation and are supported by "barons" in your empire).

Again, feedback is welcome.

I will continue working on the artwork (it's about 90% complete). I am satisfied with the flow of play when I do AI vrs AI and there seem to be no bugs. I will look at balance as feed back comes in.

Two main tasks remaining:
- randomize Viking invasions as to location, time and strength.
- Try to create a Custom Game menu so scenario attributes can be chosen more easily (ie. not having to use 1 map for each game speed).

I don't seem to be able to select a tech to research on the first turn (clicking "Choose Research doesn't bring up the tech tree), and thus can't progress into the scenario. Has anyone else had this problem?

The only other mod that I have on is EUI.
Version 9 updated on first post.

- Irish Missionary changed so it suffers much less attrition than other Missionaries... this will allow it to dig for Relics in foreign lands without dying so easily.
- Changed Handicaps... settings were too difficult for small kingdoms. They can have more units now without going over the supply limit. It is a flat number and so should have little effect on wide empires.
- set open border trading to nobility from civil service. Too many great musicians were sitting around with no place to go.

Still figuring out how to randomize the Viking attacks. Working on artwork as well... how many different icons of Ship making facilities can one find? :)

I updated Version 9 to correct a Database error in Handicaps as of July 17... uploads before then may have an error on certain handicaps.
Logs don't show any errors. Nothing unexpected (except, what is city banner manager?... just that there was a transfer of a city between a subkingdom and its civilization ally just before the crash...).

When Deira captured York... it transfers the city to Northumbria by design. At that time, there is a ownership transfer via lua and also the Northumbrian capital moves to York. I have never had a CTD at this point... but perhaps something to do with a mod you are using that does something with Citybannermanager may have been unable to handle it.

I have never seen that entry routinely in my lua logs... and I have play tested hundreds of times.

Are you using mods... scenario doesn't play well with them, especially dll mods.
I'm up to around turn 225 with Alfred and am starting to build the elements to a "science" victory. Fighting off Viking invasions is a blast. I love the complexity, the new units, the challenge of resources, and the map. It's also replayable. The main problem I have it with my slower computer. At this point, it's a couple minutes of waiting for each turn, and that's not really worth it.
