I know its nothing new but I've been kicking around the idea of starting a 40k campaign for a while, hopefully something with a map like Urban Conquest or the first Dawn of War PC game. Maybe we could even implement some campaign systems/missions from the Vigilus books or the Psychic Awakening books. My main goal is to have a long running campaign in the background which could help make our regular games of 40k a bit more interesting by adding in some fluff to all the random battles. Basically how I imagine it working is by having a large system map with multiple planets divided into several territories, something like this picture which is from Dawn of War.
On this map we could have multiple factions each vying for territory which is gained by winning battles or completing certain objectives.
For the factions it would probably be something like:
Since there are more Imperium and Chaos players than the other factions, faction mechanics on the campaign map would work differently for each faction. For example, the Necrons would have a Tomb World or Tomb World territories that can't truly be taken over on the map. The Orks would be a menace, caring more about getting into battles than actually taking territory. Tyranids would have a Hive fleet to coordinate their attacks from as well as Genestealer cult uprisings in Imperial territories.
Anyway, this isn't meant to be a competitive tournament or anything, just a fluffy experiment I would like to try if people are willing to participate. I could keep track of the campaign map and post monthly updates here as long as you guys can provide me with the results of your games and make some decisions from time to time. After a while, I think we'll naturally have some missions pop up that make narrative sense in the campaign setting which players could try and tackle leading to fun consequences and some narrative progression.
