What happened to that awesome franchise Halo? Who now owns it? Complexity and solely? Who uses the intellectual property to further there other products? Would you want to give them your next baby too or hopefully retain most of it? Even if the decision was just made out of spite? [spoiler]Microsoft is the answer. They own all intellectual property relating to Halo. They use it and it's characters for profit in other areas. Cortona phone assistant, Spartan browser. They also took bungie employees to make 343 studios to make more halo games. As well as forcing Reach. I'm not 100% positive on this. But I recall Bungie being done after halo 3 and Microsoft wanted another game. Hence Reach. [/spoiler]
