Hey everyone thanks for the nice comments so far. I'm leaving my own comment as a loose representation of how we function as a group working on this mod, and where some of our thoughts have come from.
In the beginning we added a few items and mobs before we really even had an idea of what we wanted the mod to be.
Then, we decided we wanted our efforts to be focused on mythical creatures. Not just made up stuff, but the urban legend type monsters we found most interesting
We also wanted to include different real-world cultures, to maintain a nice variety in what we added.
As we come up with mobs to add one of the most important things we do before we make it, is to try our best to add a function as well. It's not very fun to just add in a model that spawns somewhere in your world, and give it a vanilla drop. Whether it is a camouflaging monster or someone who shyly follows you around, only to hide when you get near, we try to add gameplay and or thematic elements to all of our creatures. This is also a good way to annoy our coder, because we come up with grandiose plans and make him find a way to code it in.
Then, we decided to add in player classes. This is an element of the mod I am personally most excited about, but it still needs to be fleshed out as it is in its early stages. As this was first being implemented, we also decided to go with the theme, and select some of the pre-existing mobs to become more fleshed out. We have added in custom villages with npc's and exclusively traded commodities. As of now the elves and dwarves are able to be traded with, and will spawn in custom villages. Several more village(r) types are planned.
Thank you all for reading this wall of text, even though we have a good deal completed already we have a lot of plans for the future, and thank you for the continued support. No release date planned right now. Once it is however, and we stop focusing on adding new content, I believe we do plan on updating the mod to newer versions of minecraft.
