King Midas had a way with, well, anything. According to lore, the stately one could touch inanimate objects and turn them to gold. The Xbox-equivalent of King Midas' would be Bungie's Halo universe. Put those angelic words on literally anything - including but not limited to graphic novels, toys and even rock bands (as evidenced at Microsoft's press conference last night)- and you have an instant cash cow.
An RTS based on the Halo universe? Why not? It sort of worked for the Lord of the Rings franchise, and it seems as though Bungie's baby has a little more of the Midas touch in the gaming world than Baggins and Co.
