im not sure i like the idea of being able to make a single bridge as tjhe only point of attack on your city. as a defence its too powerful. everyone would do it. there would be no personal touches or inovative defence. everyone makes one bridge and puts all defences around it. sounds kinda boring to me
GM-ing of crops is rife yes? so why have i not yet seen a 10ft killer tomato? to me thats just lazy!
