some (Nintendo) seem to believe HD comes at the expense of gameplay, Tetsuya Mizuguchi believes that the increased resolution can give games even more emotional impact. He remarks on a feeling that many of us have had, when watching a movie we've seen over and over, watching it again in HD can give an entirely new feeling. Sure playing Mike Tyson's Punch-Out on NES was (and is) fun, but this is 2006. High definition allows you to appreciate lumping up opponents faces in Fight Night Round 3 in ways the SNES never could. Even simple games like Geometry Wars are even more inpressive on HDTVs, there's nothing like having millions of multicolored geometrical shapes chasing you on an enormous screen with no blurring whatsoever. In the interview with Games Industry Mizuguchi goes on to add that he thinks other elements like 5.1 surround sound and particularly online connectivity combine with high-def as a new frontier for gaming.
This is the man who created such classics as Sega Rally, Lumines, Rez, Manx TT and others. He understands the importance of good gameplay, but instead of shrugging off HD as a niche product with little value, he's willing to acknowledge the possibilities and look for ways to enhance gamers experience, rather than limit it.
