I'm going to regret asking, but how did he "ruin" Nintendo?
Everything devolved in to being based around gimmicks rather than improving the core experience. When Nintendo ignore gimmicks (Mario Galaxy) they still make fantastic games, when they feel the need to tack things on to justify the gimmick at the time (Skyward Sword) it's directly negatively impacting the quality of games I want to enjoy.
Not to mention it's under his watch Nintendo have completely failed to remain relevant in the online area. Don't get me started on their digital distribution policies.
