Welcome to Librarium Online!
I'm going to be starting a Campaign featuring primarily Orkz and Imps. I'm hoping to avoid an event-based campaign (I don't like the idea of using a Tree of pre-determined scenarios...too fatalistic), and I am drawing up a rough planetary map to allow for operational-level strategy. Since I'll be using regular 40k for most of the battles, the fights will be small-scale (relatively, anyway), and will probably focus on a specific area (which means making other scaled-down maps).
Anyway, if any of you have ever run such a campaign please post tips and suggestions
