Dear 343industries,
in case you were planning to port Halo 3 to PC, let me give you advice to make it better.
In my opinion, Halo 3 pc should:
-include all DLCs and multiplayer maps
-include Halo 3 ODST expansion disk
-include a map editor (like Forge but with more features)
-be graphically improved (HD textures, Antialiasing,...)
-include online and LAN co-op
