I havent played Wasteland , the new or the old demo (the link was broken when I tryed a few months ago) but I've seen some of the screens on your site It looks good except I think the old one had more ballance between the colors , now the buildings look less colorful.
I think its great (from the screens,story...)and you should keep working on it ,instead of leaving it lifeless like the most RTS theese days

PS.: A good idea will be (like in my favourite from the C&C series Tiberium Sun) to create a ranking/leveling system , if a unit kills more than ... units it becomes more and more powerful up to a point where that unit alone can kill 5-6 low ranks of his type. (I loved that part in Tiberium Sun and it gives a chance when you have 10-12 units and no longer have a base to win the game with them)
