What would you have chosen?
it's pretty obvious that they couldn't buy off both as exclusives so they had to pick one. and we all know Microsoft was in cahoots with S-E to at least secure some sort of S-E game for the 360, that they chose Infinite UnDiscovery but also i'm betting a timed-exclusive for SO4 just because S-E knows japanese gamers know that all Star Oceans were released on the Playstation so they have to cater to them too. Thus this timed-exclusivity
But if you were Sony, which of the 2 would you buy off?
