Decided to give people something of a status update.
Currently, I am still working on the non-entity creatures. I've had to re-do nearly all of them from scratch due to massive problems in the original RAWs. I'd say I've done at least a third of them, however, and the rest will be done soon enough.
After that I will alter the advanced worldgen presets to remove content like the regional interactions, night creatures and such, as they will be replaced by mod content, some right after I modify the worldgen presets, some later. Non-real world plants will be renamed to be more generic, since there is little information on plants in Warhammer (it focuses on battles, after all). A few new stones/ores like warpstone and gromril will be added.
After all that, I'll start working on the dwarfs, and when they are done a version will be released. That version will contain no civilizations other than dwarfen ones, so the only threat to forts will be from necromancers. After the dwarfs are done, I'll pick a new race and repeat the cycle. This should guarantee somewhat frequent releases that are also stable and playable.
Unfortunately, many things will lack sprites, so if you do have spriting skills, PM me.
