Signature Weapons [4.0]

This mod aims to increase the individuality of empires while maintaining the highest possible level of compatibility with other mods and without changing how weapons work. All it does is make the first technology in every line of weapons into a rare technology, but upgrades to that type of weapon are still normal technologies. This reduces the number of different weapons a typical empire has, but allows you to keep the weapon types you do have up to date. And of course you can eventually still research them all, if you want. HOW IT WORKS The follow technologies are now rare: - Arc Emitters - Autocannons - Disruptors - Kinetic Battery - Mega Cannon - Particle Lance - Plasma Throwers - Proton Launchers - Space Torpedoes - Swarmer Missiles Other weapon technologies remain normal technologies. All empires will have access to lasers, missiles and railguns, but other weapons will be rarer now. Upgrades remain normal technologies too, so once you add a weapon to your arsenal you shouldn't have trouble keeping it up to date. Additionally AI empires will choose one out of autocannons, disruptors, plasma and swarmer missiles as their signature weapon and will not research the others. The choice is based on the empire's preferred weapon type and available rare resources. This also helps the AI in a roundabout way, by forcing it to focus on a smaller number of weapon technologies. AI will normally try to research all new weapon types, regardless if it'll actually use them. But with this mod it should only research weapons it will actually use. OTHER CHANGES The mod also introduces a few other changes: All weapon technologies except point defense weapons are now among the least common and most expensive technologies of their technology tier (subtier 3). Point defense weapons are now among the most common and least expensive technologies of their technology tier (subtier 1). The Space Torpedoes technology now requires the Fusion Missiles technology.
