In recent times I have considered shifting gears on this and making it Old School Essentials compatible. In this guise it would be a setting book, not just a collection of resources.
The jury is still out on what I will eventually do.
Here's a list of the classes I know of that are slated for this collection. Some will be stricken from the list because I've already done a version, probably in Black Pudding. I italicized the ones that are probably going to be cut from the list.
Dwarven War Priest
Of course making this a Labyrinth Lord resource book instead of an OSE setting book has a very strong appeal for two important reasons. First, it would be easier. And I need to practice biting off things I can chew. Second, given that OSE makes LL a bit obsolete, it would be a nice send-off to my favorite game of the OSR movement. It is entirely possible I'll never do anything specifically for Labyrinth Lord again. No shade at Dan Proctor... he did a major solid for the entire RPG world by publishing his retroclone. It's just that the benefits of OSE outweigh my already powerful nostalgia for LL. I feel a great need to give LL some love.
