I think they kind of respect their own franchises, trying hard not to destroy their fame for quality, improving on them only if they have something novel to introduce in the series or a new way to do a particular game, like non-linear dungeon order on Zelda: A Link Between Worlds, or a 3D Metroid when they did Prime, etc. They don't make the same game in different clothing just because they can. And their games generally age well. A different approach when compared to most game makers nowadays, surely. But one I can definitely respect.
