After AoA is published I still want to support WAB and here are my thoughts/ideas how to proceed
Army Books 1-4 (3000BC-1500AD)
The huge number of downloads (hundreds, thousands ) of those WABForum Army Books make me think it is a good idea to step forward with book 1-4 to delete all lists covered by the AoA (and the upcoming pdf collection from Martin) and merge all remaining lists into one book. I expect roughly ~100 lists for that. They all can be seen as candidates for official lists as soon as they are chosen from Martin to be worth to add them to his collection. Adding them to a pdf collection is much easier than adding them to a printed supplement project, me think. I don't have a point calculation for the AoA units so the points remain the same. Also the listing of each unit on it's own instead of the AoA new way to list a bunch of units and cover all equipment, additional eqipment and special rules. I prefer the old style of each unit including stats, equipment and rules seperatly.
Army Book 5 (Renaissance)
This period isn't covered other than with the ECW book. The planned "Warhammer Renaissance" book seem to be lost in the pipeline of Forgeworld. Sadly, there is no rumour about it or any hint that it will be published one day. I still think the period is worth to be played, very interesting and can be covered by the WAB rules with some additional special rules. As soon as the "Napoleonic WAB" project reaches version 1.0 I plan to start this as next project as a kind of supplement or army book. With that book all six major periods (biblical, ancient, dark age, medieval, renaissance, modern) with lists for WAB.
Army Book 6 (Modern)
There are three major theatres of this period SYW/Napoleonic/ACW. With the expanded Napoleonic Wars book we still create, one of those theatres will be covered, but SYW and ACW are very different, so they should be handled seperately in "supplments" instead of an army book, me think.
I still like the idea very much to be able to play all periods with WAB. Another motivation for me to create all those books is to have a future event where teams of six players (country or club) play against each other, one army per period. But contrary to other systems/team events it still should be WAB, which means a bit different and more relaxed/fun and nicely arranged tables, terrainwise. So each period should be handled on it's own with a campaign or focus on a war with armies only from that conflict to have adequate armies and games with a historical touch and scenarios. Adding the results/victory points of each period per team (however they are earned, this should also be up to each period) give the ranking per round. Something like this
