They just did Neir or whatever it was called. And if I remember, it didn't go over that well. Square's trademark seems to mainly be stick with what works and will guarantee money. And every once in a while try one thing new. EA got a lot of flack for similar business models. Until someone makes the point that the new sports game is basically funding games like Mirror's Edge
Final Fantasy and Kingdom Hearts funded The World Ends With You, Nier, and The Last Remnant
