It’s not uncommon for a game’s scope to reduce during development, but Bungie had a unique problem. People who worked on this project say that one of Bungie’s fundamental issues over the past few years has been the game’s engine, which the studio built from scratch alongside Destiny. Four sources pointed to Destiny’s technology—the tools they use to design levels, render graphics, and create content—as an inhibiting factor in the game’s development.
“Let’s say a designer wants to go in and move a resource node two inches,” said one person familiar with the engine. “They go into the editor. First they have to load their map overnight. It takes eight hours to input their map overnight. They get [into the office] in the morning. If their importer didn’t fail, they open the map. It takes about 20 minutes to open. They go in and they move that node two feet. And then they’d do a 15-20 minute compile. Just to do a half-second change.”
People who have worked with Destiny’s tech say the company is capable of powering incredible things behind the scenes, like player matchmaking. It’s also clear that Destiny is one of the best-looking video games ever made. But as a tool-set for designers, sources say, Destiny’s engine is subpar, and creating new maps and missions at Bungie can be grueling for developers.
