Okay, so Siegus is simple enough that you don't need to be a well practiced strategist and well....I like that! Yet I've noticed some designs in your game elements which balance out the playing field, like you cabn't just use shitloads of archers to storm a base because as soon as they start shooting a fort it generally kills them all. I did find myself, however, using archers and defenders in combo throughout most of the game. I used the legionaries to some effect but they just didn't satisfy me. I also like how on the last upgrade for x3 amount it would decrease costs making it more efficient to buy in bulk...which made players want to upgrade more.
My only issues are two things...1- gauls were boring to play.
and 2- archers were solution to almost any situation after you max their range.
4/5 and 9/10.
