I've been thinking about projectiles in Empire at War and it seems that from playing the game it seems there is only 3 types of projectiles. Those like ion cannon that only do shield damage, those that penetrate shields those that do hull damage. After looking through the xml files I have discovered that some projectiles that have energy damage (it's how the ground ion cannon works) which with certain xml code, the ship can lose it's engines, etc. In general there are a lot of nuances that go into the projectiles, (you can even have death projectiles, that spawn when the main projectile dies!)
I find a lot of this interesting as for a strategy game there is a great potential here to incorporate within the missile, laser, and rocket projectile categories new variations of these to create different projectiles to have unique projectiles. It's something I think this game could use to build around adding more and more ships, which I feel most mods get lackluster when adding lots of ships that have similar weapons.
What do people think? (Hopefully everything above made sense)
