That's a great idea but, like you said above I would have alot of other stuff to do so I wouldn't have alot of bricks. The walls would use a ton of bricks. I would not have much to make artillery with. I'm going to hvae 9 grey baseplates for the inside surrounded by some green baseplates for the outside. I would put some clones with turrets on the green baseplates instead of artillery.I also have the spongebob hospital set and am going to use the ambulance and the thing to carry spongebob on for injured clones. I might even keep the fish doctor just for laughs!
I'll tell you when I have some more parts planned out. Suggestions are welcome.
