They couldn't stop the flood, a glorified fungus, without wiping out there entire civilization.

[i]The Flood is a lot more than a glorified fungus. The Flood is the current version of the Precursor species. Add to that, the Flood's strength is directly related to the strength of its victims. The Forerunners were insanely advanced, and because of that, so were the Flood. The parasite has access to the collective knowledge of all it has infected. They are essentially omniscient. The Forerunners were also betrayed by their hyper-intelligent AI, Mendicant Bias, when he was corrupted by the Flood. He took more than half their entire fleet with him. The Forerunner-Flood War is a lot more complicated than you seem to realize. You're not even talking about Halo vs Star Wars anymore. You're talking about things that have beaten the Forerunners without any understanding as to why. Can you please give up? It's obvious that you've lost, and this is getting boring. [/i]

I agree with the boring, this has gone on for a while and I will agree the flood are more powerful than I originally put it. They would probably give the halo universe a run for there money actually as they are an enemy designed to raise themselves to their opponents standards. Sith flood would be interesting. Seeing as this argument needs to end as neither of us will give way I will conclude that the flood vs force corruption would be a pretty even fight. Or early on in the battle the forerunners would drive their lower tier tank into fisherman's bay by activating the halo rings so no one wins.

[i]Forerunners chill in Slipspace, casually blowing up the stars of every important solar system in the Star Wars galaxy. No Forerunner dies. You've had no rebuttal for this argument, so I'll take that to mean that you don't have a counter-argument. GG[/i]

Forerunners can't blow up their own stars as they would lose their systems. Star Wars takes forerunner systems with little effort as the forerunners are "chilling in slipspace." They then drain forerunner resources and set up shipyards as they wait for the forerunners to make a weapon from their empty slipspace vacuum that was precise enough to not blow themselves up.

[i]Lol what's stopping them from blowing up stars? This isn't their galaxy, remember? Shared environment. They can blow up stars with impunity. It's not their galaxy, so why should they give a damn? You're just grasping at straws now, but I'll humor you. Let's say the Star Wars factions successfully take some Forerunner planets. Big deal. Forerunners blow up the corresponding stars, then make new ones. You are aware that Forerunners can create stars and planets with next to no effort, don't you? So they just blow it all up from Slipspace, and then make new stars and planets to replace the ones that are lost. GG. [/i]
