Aight that's a good start
I can think of more then ten sets they could make already
-Each of the buildings inside the castle and comes with Minifigures corresponding to that building (Archery range get 2 archers and 2 albas for example)
-A battle pack like set, "Fight for the Tower" Comes with lots of various minifigures (At least 8 Figures), the tower rock, a wall and turret
-The castle that can hold all the other building sets
Umm, lets say its only 1 year old, and that the difference between stick war 1 and stick war 2 is 2 years, and in 4 months, they would have completed stick war 1, and they would forget the game.
If there ever was Lego SE, I'd like for the units to actually have faces and uniforms, not black. I can see some arguing with this, but I've made some black stick people with legos before, and it didn't turn out well.
