Quick Quotes: Battlefield 3 multiplayer benefited from 100% in-house development
"It’s a world of difference to work together at one location. The whole game is made at DICE in Stockholm. It’s great having the guys running around, talking to each other. Co-op, for example, is actually based on a lot of the philosophy behind multiplayer. Teamwork is never forced, but we have different gadgets and mechanics that help you work together. Just the co-op and the multiplayer guys talking to each other, what you should be doing, it’s a much more coherent and better product overall." - BF3 producer Patrick Liu on the differences between Battlefield 3 and Medal of Honor multiplayer development (via MTV).
