This is the official Imperial vs Alliance thread for the Homeworld 2 mod. I'll start. I think that the Alliance is vastly superior. Why? Well, for one thing individual ship quality is superior. Just look at the fightercraft. Then, you have cost. Alliance ships are typically cheaper to build than their Imperial counterpart. An MC-80 can trade fire with an ISD I on nearly equal footing. Which costs more? The ISD by a lot. I acknowledge that the Imperials have the real heavy hitters. The Vengeance SSD. The...*gulp* EXECUTOR SSD, which I have never seen in-game for its massive build time and cost but am going to try tonight. The ships that blacken the sky. That make a rebel commander crap his pants. BUT. These ships are enourmously expensive, and if they are destroyed, the destruction can cripple an Imperial foe. Indeed, what with the cost of the incredibly powerful Executor SSD, an Imperial player risks ALL for these ships. The rebel commander's ships are typically faster, and much more technologically and aesthetically superior. Challenge that argument, impies
