Specify if you have any other companies in mind and reason out. :P
I'd say mine is Square Enix. Square and Enix used to be fantastic RPG developers. Now their games have been received mediocrely (except Nomura's stuff or similarly Nomura related games) and they're trying to "westernize" themselves more (and we know they're fantastic being Japanese developers).
