i know halo was orginally suppost to be a RTS(real time strategy) like command & conquer and starcraft.

Well you know how C&C was etablished then they created C&C renegade where you play as the GDi commando like a FPS.

What if they did the vice versa with halo.

Imagine a RTS game humans vs covenant. Roll into enemy territory with like 12 pelicans full of marines and a few spartans.
Spartan is the class soldier that master chief was
rolling around with a pack of warthogs (almost like NOD buddies from C&C)

I even see potential as the flood as a 3rd race too. Oh the possibiltys are endless....................
