At Peterborough wargames club, we have just started a WAB Arthurian campaign. We are using 1000pt war bands with larger numbers of characters to enhance the 'heroic' feel of the game and with some other slight adaptations to the core Arthurian lists, which we realised we needed when we tried a similar campaign a couple of years ago with these 'character-heavy' war bands.
Anyway, check out the link below to see some background narrative and the info about how round 1 panned out. If any of you want access to the documents we are using, you can have them. Please pm me an email address and I'll send them to you. We are playing round 2 on Monday, so I'll keep you posted how it all goes...
