it was worth it. There were some customers that picked the Xbox360 version over the PS3 version because of that. And they showed that former PlayStation related franchises are on their way to the Xbox360 + extra content.
Even if they won't get any revenue at all, the marketing aspect was pretty big. Let's say they will receive 20Mil with that. So they spend 30 million to show the world that the Xbox360 gets a lot of former PS-only-games.
Imagine not having GamePass on your console...
