able.  Perhaps master chief collection or Gear of War 1,2,3 would be possibilities.  This would certainly help to create more fans of these respective franchises.

These series (especially Halo) appearing outside of MS platforms (XB, Windows) would be a pretty big development.  A positive one, IMO.
