I've been playing videogames since the NES era, so nothing really surprises me anymore. New experiences... it's very rare to find them these days, and it's been this way for at least five years. After playing so many games over the past 20+ years, I know how games work, I know how they all control, I know how they all play out, I know what to expect from pretty much any game I play, no matter the genre or developer. Fortunately I don't need a game to be a new experience for me to enjoy it, but the sense of wonder I once had playing games will never be had again. Though to be fair, part of that comes with growing up, but even so, I've played too many games.
Perhaps Nintendo feel somewhat similarly. Maybe they try to come up with crazy new ideas for their systems because they, too, are looking for that new experience even after so many years and so many games. Sometimes things work out, and sometimes they don't, but no matter the outcome, I applaud Nintendo for all their gimmicks, and for having the guts to try then even in the face of doubters.
