There's no better example of "less aware of the fans are looking for" than
Prime 3 was great. Not perfect, but it was the best of the 3 in at least a few specific ways. I don't think anyone is really that worried by that game. It's chibi team soccer that's causing me concern over whether he really understands what is and isn't Metroid.
Retro really worked hard to understand Metroid before working on Prime 1, apparently spending entire days in conference calls with Nintendo just discussing the series until they knew it inside and out, and I think they and Tanabe worked really well together. But when working with new developers with no direct Metroid experience and no deep base of knowledge like that is a different situation. They really depend on Tanabe to guide them, and FF makes me question his way of thinking about the series, even if it is a spinoff. Hoping with all my might that I get proven wrong.
