I was watching Robert Florence's Chaos in the Old World promo video again last night (for the nth time). If you haven't seen it already, then you should get your cave(wo)man ass outta the bunker from time to time. Watch it here. In it, Rob mentioned how the Chaos' Gods' dials were ticking away as if they were their own separate game (which got me to thinking about Dune, but that's another story). Now bear with me for a minute as this won't be a thread about Chaos in the Old World (Mr. Lang's other excellent game set in the Old World...you should check it out). I was thinking...what if the multiplayer rule set for Warhammer: Invasion was its own game-within-a-game? Kinda like how the melee play for AGoT LCG is, but more involved.
In my mind's eye, this could go two ways: a weird RPG-esque adventure path (think WoW, but with armies...maybe W:AR?) or a conquest-slash-RTS-kinda way. Or both.
The former road may be too funky to process it in words, but the latter definitely has possibilities.
You can have a map of the old world as the multiplayer board and preferably without fixed starting locations for races.
Certain card interaction, such as I don't know, killing/discarding X opponent's cards, may allow you to take over a neutral territory or part of your foe's domain. After a cleverly designed timer has counted down to zero, you can see who has the largest chunk of the Old World and pronounce him or her as the victor. Each faction may have their own thing (or agenda) happening too, such as Chaos corrupting the land for extra points/advantages, Orcs ravaging the country side and fighting things, Dark Elf enslaving/sacrificing, High Elf restoring and purifying, Dwarf protecting and adding/striking off grudges, and Empire making alliances & proselytizing. Or you could enlist the aid of Neutral factions via simple perks, such as the Ogre Kingdoms granting a small bonus to fielded neutral warriors. All of this would have to be fairly simple, or the rule complexity would overload the potential thematic cool that a game-within-a-game could bring to table. Should Mr. Lang go down this road (oh please, please, please!)...I have utmost confidence that he will pull it off with flying colors.
The reason I'm even talking about multiplayer rules at this point is because: A) There is a demand for it. B) The upcoming Assault on Ulthuan Deluxe Expansion doesn't seem to sport rules for multiplayer play from the look of things (a big MEH! from me if that's the case). Since there is less than a month to its release, FFG would have mentioned it by now. At any rate, if B is true, then let's hope there is another Deluxe Expansion in the near future (oh, I don't know...a faction one such as for Dwarves a la AGoT: LoW) which includes a fully functioning multiplayer rule set.
