@Ajrep:

I agree with PerhapsTheOtherOne: as much as I like crossovers, I don't think we should do cross-canon within our own project. Keep Earth to Earth, RWBY with RWBY, and Halo with Halo (I saw you had a DMR as a weapon).

That is not to say you can't reference those, so long as the reference and/or joke makes sense in-universe.
