Just wanted to inform everyone (well, all three people who really seem interested) that after some serious thought, I'm probably not going to work on Nature+ anymore after all. It was a fun project, but I've realized I've basically reached the point where if I add or change anything else, I'll be getting a bit to far away from the original premise of the mod for my liking. Nature+ was always mean to just add some more creatures and make them make a bit more sense, and I think I've achieved that goal nicely.
That being said, I'm not done modding Dwarf Fortress. I have a new project in mind, and I intend to take the lessons I learned from Nature+, as well as the feedback and advice I received from everyone, to create a (mostly) total conversion mod, one which is hopefully less buggy and better organized. I want to thank everyone who showed interest in or downloaded this mod. I'll see you around.
