So your first order of business will be to figure out which of the non-playable Elector Counts is friendly towards you, and which aren’t. Start a campaign as the Empire and one of your main victory conditions is to control a specific set of regions, through ownership, alliance or vassalage. So we built many minor factions for each race, gave them personalities of their own, and while the playables are the stars of the show, this supporting cast, whether noble, capricious or downright bloodthirsty, brings a lot of texture and colour to your campaign. Take the Dwarfs – there are a bunch of factions in the lore such as Karak Norn, Karak Hirn and even the lost clan of Kraka Drak, surrounded by chaotic marauder tribes way up in the wilds of Norsca. In short, we found ourselves being pretty choosy about which races we would concentrate on making playable.
It was almost like working on a bunch of historical eras simultaneously. In the development of Total War Warhammer, we quickly discovered that to best reflect the diversity and variety that each race brings to the tabletop game, we’d have to design unique campaign and battle mechanics, styles of play, and ultimately flavour.
