There are great contributions here, I would be happy with most of them replacing any official GW campaign elements we got so far. Some of it are quite experimental and I want something "safe" to begin with. I consider the original Necromunda campaign something safe to fall back to. That's why I want to mainly use those as replacements: Income Tax Underdog XP bonus XP system Territories Now, I find some parts of the new Dominion campaign system interesting. Possibility to have more expensive fighters, weapons and equipment. So I reduced the income tax slightly. And some of the new territories look interesting, so I kept a several of those. And to support the possibility to have horde gangs, Income Tax can be tweaked to have gang rating as an alternative to gang size.
