I wonder how much Xenoblade Chronicles X cost to develop. Probably slightly over $20 million, huh ? Nintendo will probably keep its marketing costs fairly low, but who knows, we could at least get a TV ad out of it. That would put it at around the same cost as Uncharted with $20 million. We knows Gears of War 1 was around $10, its sequel is $12 million and Bioshock 1 is apparently close to $15 million. 1st Party dxclusives such as God of War 3, apparently cost around $44 million, Gran Turismo 5 at $60 million and Heavy Rain at $40 million ($20 million of that is from marketing costs). For known open world games, Crackdown's around $20 million, Final Fantasy XI cost $40 million, Witcher 2 is apparently $10.3 million, Watch Dogs is $68 million. Then there's Destiny. It apparently cost around $140 million... and that only includes Bungie's development cost and $1 million marketing budget not counting Activision's separate marketing costs.
