The description helps, at least I got some idea where to go from here. Just started out this week playing and got stuck at several points. One of them being requirements for building a trebuchet. I read in your description that you need a barracks, but there's more that's needed (forgot name). Just need to find out how to get that.
This makes me wonder wether you'll be making a tech-tree of some sorts for the three races or that you will have players find out for themselves.
