far as me personally I'm indifferent. I'm more familiar with the tools available in the earlier era as a solid fourth of my CoC sessions take place in that time but I have done plenty in the modern era (which generally take place between 2000 and 2010). Although we have some pretty cool technology now such as curved barrels on guns allowing one to shoot around corners, and the US Navy was doing pretty well on making railguns, the latest prototype able to fire 23lb ammo at a speed over 5000mph.
