Amusing, but breaking everything down to the point where all in life is optional - breathing as well btw - is hardly relevant.
With renown hearts, you can pick the order and the amount you want to do of each yourself, I'd say the later is a minor innovation over a regular quest, while the former would simply equal doing 3 quests.
But the activities themselves do repeat throughout the different locations and just because you dress them differently doesn't mean the activities themselves are different. I don't have a problem with that, there are only so many activities you can offer in a specific game, however, calling it innovation is what i find hugely exaggerated. They don't really differ from each others (or other games) once you understood their repeating pattern.
