[2024] MOVED: Saving 7D2D Loop

You might try Undead Legacy or War of the Walkers. One I really enjoyed for awhile was District Zero which replaces the zombies with robots and changes some of the fundamental vanilla rules.

Actually, I recommend that you download Sphereii's modlauncher and just explore the list of mods that are included in it. It makes trying lots of different overhaul mods easy to do and you can see the whole list of those mods that are updated for A21. Maybe one will really gel with your group.

Oh...also...

Since it seems like you have at least a little experience modding since you were considering doing it yourself, you might consider downloading the Darkness Falls mod and simply remove the demons from the entities. That would be far easier than modding in your own version of learn by doing. That's if none of the other mods are as appealing as Darkness Falls has been for you up to this point.
