What I think is interesting about this mod and all the other "Specialized" mods I've created is that I don't give you a new technology tree with tons of new features one better than the other so, when you unlock the last one, you'll use only that one. Instead I want to give you different new features for different purpose and with different capability so you will need to choose which one is the best for you in that precise scenario.
