OXM - You know a videogame's a big team effort when the people crafting different bits appear to have nothing whatsoever in common. Lord knows how an environment guy makes small talk with the man responsible for the iPad integration, for instance. "So you're in tablets? Awesome. I just drew one of those. It's ten million years old, made of basalt and the key to Master Chief's victory over the Reapers. Or the Zerg. Or whoever. Sorry, plot isn't my thing. You'd better ask Frank."
