"We were kind of interested in Source early on because it’s very familiar to our designers," said Richard Baker, a software engineer at Respawn who previously worked on Call of Duty 2, Modern Warfare and Modern Warfare 2. Source also suited Respawn’s desire to hit a constant 60 frames per second on both the Xbox 360 and the PS3, where other third-party engines weren’t up to the task. "The ironic thing is that we wanted an engine that would work on PS3, because that’s the riskiest platform in current gen. When Portal 2 came out and it seemed to be a pretty decent PS3 game, that was the point when we decided to go with Source. And then we stopped supporting PS3."

They choose Source due PS3 and the game supported PS3 until E3 of this year when they stopped to support it.

Further confirmation that rather than funding a game that would've otherwise never would have existed, Microsoft instead went out of their way to pay to make sure a game DIDN'T come out on consoles it otherwise would have.

Just another anti-consumer practice Microsoft needs to stop if they don't want to be seen as anti-consumer.

As much as I dislike Nintendo and as anti-consumer as they are in so many other regards, Bayonetta 2 is an example of a 3rd party exclusive done right.

interesting.  I always thought it was odd that they went with source.  So yeah, you are right that they chose source with ps3 in mind, but it sounds like it was dropped long before E3.  They moved it from a current gen title to a next gen title and then dropped ps3 (and technically 360, but EA pushed that to another studio).  

I guess it was PC/360/PS3 to PC/360 (MS paid for that)... so when they announced Xbone they moved to PC/360/Xbone

Titanfall is being developed since 2011 or before that.

except  it almost guaranteed to fail to sale and will be a big hit to their profit margins... 

I was under the impression that the MS deal wasn't in place until after E3.

Done right for the consumer, I mean. Who cares about Nintendo's bottom line?

I wouldn't even care if it did come to Playstation. It looks like COD with mechs to me. FPS is a tired genre at the moment

well i guess we'll have to settle for the PC version of this "game world changing" FPS. feel bad i wont be able to see and enjoy the superior xbone version.

Where does it mention PS4?!
