Top on my list of features is special skills (Made the build up bars already) Pegasus Skills will change the weather, Unicorn Magic etc.
I also want different areas, like clouds, and an area for a castle and an Alicorn to rule with there guards.
More Jobs, More buildings and some economic drive is a must.
I love the idea of building times, didn't think of that! Now its getting bigger and more iso, I think it has to be done ^_^
