Does anyone know how I can remove the option to build SDI from the game? I hate it, I don't want it and I don't want the AI to have it. It's ridiculously effective and completely unrealistic. Even with Exavier's composite mod, which lowers the effectiveness of SDI to 60%, I'm losing 5 out of every 6 missiles I fire. SDI doesn't work in real life and I don't want it to work in the game. If it can't be removed, can someone tell me how to reduce it's effectiveness to 0% or something? P.S Anyone know of a reason why the AI wouldn't build nukes when it can? In my current game all the civs have the technology but I'm the only one producing nukes (and using them). I'm pissed because most of the ones I fire are shot down. The thing is I WANT a nuclear war and the computer won't play along.
