"No other engine" can make Battlefield 3, says DICE

Frostbite 1 was a decent engine. Wasn't half-bad. Used for Bad Company 1 and 2. But DICE waited until Frostbite 2 came along before Battlefield 3 could really get going So why is that, executive producer Patrick Bach?

"The short answer is this: No other engine can build a Battlefield game," Bach told Joystiq at last night's EA showcase at GDC.

"If you don't have the right tech, you can't build the right experience. The Frostbite engine is solely created to make Battlefield games."

Bach insists that while authenticity is key in games, the fun is the main point. If there's no fun, don't bother.

"Authenticity is very important for all Battlefield games ... but it's always fun first. If it's not fun, then there's no point," he said.

A new engine for Battlefield 4 seems to be unlikely, though.

"I think we learned by experimenting with these other things that the core is quite powerful. We should probably spend more energy on the core than on these experimental things.
