Forum:Forerunners/ Precursors and God Modding

I noticed that certain technologies would definitely be Godmodded, if not for one little snag: It was made by the Forerunners or Precursors. Now, the Forerunners' tech is beyond the capability of UNSC, Covies or other race (with the possible exception of the Necros, as we know so little about them, but shouldn't there still be some godmodding rules for the Forerunners/Precursors (i.e. no Precursor weapons that can cause a Big Bang level explosion and destroy the universe, even a Halo can't do that!)
