Ok, I really think we should use a four seasons system.
But would it be kind of odd i.e its autumn but its like summer or its like winter.
Or is there a way to make sure that weather patterns change for the seasons, e.g in summer there is hardly any rain, but in autumn there is a bit more and maybe if we have a somone who is willing some new autumn looking trees.

Also, just a question, what siftware can I get to start skinning?
