I must be oblivious ... but what would make a game cost that much to create?
I'd say a large part would be marketing. This should probably account for about half given a somewhat naive rule in business. Plus, they are marketing worldwide.
The other big part is just salaries of larger teams and the time it now takes to develop. Let's say a team of 25 are making a game for a year with salaries of 50,000. This is already 1,250,000. This would be a somewhat small team. I'm not sure on average salaries.
But then you have places like Square. There is a fairly famous story where one employee stated he was given a month long task of modeling a rock. This is a huge waste.
But from my limited knowledge, I could see a game costing several tens of million. A quarter of a billion seems excessive.
