I think Sony got jipped on that deal. The people that used to work for and made Bungie truly legendary are long gone and scattered to the winds. And IPs? Just Destiny. That's about it. Not worth 3.6 billion. MAYBE $300 million. Destiny does earn regularly with the mtx they shoved into Destiny, but that's all I can see. Now, what Sony COULD do, if they were smart, was use the Bungie name and renovate it HEAVILY. Build it back up to be the powerhouse it once was. Now THAT might be worth 3.6 billion. But it would require a lot of work and time to do so. That kind of perfection you get out of games like Halo 3 come only from developers that are truly comfortable with each other and work incredibly well as a team.
With that aside, Ubishit is probably next considering how much they seem to want to emulate ActiBitch.
