[quote]The three Rakatan stations in combination can provide a literally endless number of capital ships, fighters, and droid armies. Centerpoint has tractor beams that can catch FTL ships, planets, and stars and then manipulate them into crashing into each other, destroying planets and stars by collapsing their cores through gravity manipulation. [/quote] YEs, an infinite number of ships powered by a star, which is something the Forerunner find amusingly quaint. Forerunner technology, all of it, is powered by destroying early, nascent universes. We are talking power levels comparable to the big bang, the discrepancy here is simply too much. If you want context examples, the Forerunners regularly created and destroyed stars, and had the industrial capacity that makes the Star Forge look bog standard, so the Forge is simply not worth mentioning. And the forerunner had an entire defensive grid called the Jat Krula Line, or the Maginot Line, a system of planets around the inner rim with weapons designed to pull ships out of FTL and force them to crash into planets. We are talking multidimensional warfare here. The multiplayer map Wreckage takes place on a planet with such a weapon, in a graveyard of dead ships. This strategy was considered primitive, outdated by Forerunner standards, and in the end, it didn't work. [quote] Sun Crusher's hull is virtually indestructible, able to shrug off shots from a Death Star superlaser (which is able to destroy planets in a single shot). The Didact's ship was heavily damaged by the UNSC Infinity's MAC cannons. It's small size was directly designed to be able to enter star systems undetected, fire a resonance torpedo at near-lightspeed towards the star in the system and force it to go supernova, and then exit a system immediately after. [/quote] The sun crusher's purpose, destroying stars, is also run of the mill for Forerunners. Its hull is the only issue here, but Forerunner easily contend with it by making common usage of gravity field generators, stasis fields, time locks, dimensional manipulation and black holes in naval combat. A Forerunner AI would be fast enough to detect the SC enter the system and place in a containment field for light minutes away for capture or destruction later on. Dooming it to slip space would work quite well. [quote]Forerunners may have the Halo rings, but those don't do anything to droids and the advanced AI that the Star Wars universe has. [/quote] Advanced AI is relative. Cortana can calculate the position of every atom in the universe at once based on a comment she made in Halo CE. [i]She[/i] is casually shut down by even basic Forerunner military grade AI's, like Guilty Spark. It took her a few weeks to be subverted by the Gravemind. Medicant Bias would be simply out of context; he personally controlled fleets of millions and it took him 43 years to fall to the Gravemind in the same way Cortana was about too. Forerunner AI is simply beyond comprehension, and they are [i]everywhere[/i]. So nuking the galaxy from a safe distance (the Forerunners had 18 total Halo Rings, 11 of which were destroyed, 12 of which were larger and could fire inter galactic distances in straight line) is still a viable strategy that instantly removes every SW faction present except the CIS.
