I guess it is easy and tempting to ridicule and dismiss Nintendo for all kinds of reasons. For some reason or another people pretty conveniently and consistently forget how absolutely gigantic hit Nintendo DS has been. It is currently outselling Xbox One by clear margin. People who dismiss it as platform for " casual games" don't know much about DS and it's catalog. Or alternatively,don't understand what casual games are.
I've always much liked Nintendo's approach when it comes to controllers. Out of next gen controllers*, Wii U's touch pad is the only one that can bring anything to table that improves experience of core gamer in relevant fashion. Of course, since nobody but Nintendo makes games for Wii U, this is not something all that likely to actually get explored.
Western game studios and Nintendo have had fairly dysfunctional relationship for a very long time. Gamers suffer from this greatly; both Wiis have controller solutions any core gamer playing on consoles would enjoy far more than anything Sony or MS have ever managed.
ie, nunchaku+Wii Mote makes an awesome control solution. Virtue of being able to keep my damn hands where ever I please (yes it sounded wrong) as I play my games is a big deal. It makes the whole 'couch-gaming experience', which has always been so crucial for justifying WHY you'd use a console to play a game in 1st place, much more convinient. Yet, nobody but Nintendo ever really utilized them.
It is a shame people haven't been able to experience their CODs and GTAs with Wii's controllers. Returnign to PS or Xbox pad after some nunchaku love feels mildly depressing, always.
It is easy to start spelling doom for Nintendo when EA and co opt out. In doing so, we kinda forget Nintendo's history with core titles of their own. It makes a track record you can not even compare to anything game studios tied to MS or Sony have ever managed. Part of Nintendo's inability to woo western studios has to do with it's ridiculous, conservative jurassic approach..and part has to do with not-entirely-unjustified arrogance and belief they don't really need multiplatformers.
*ofc, it is pretty questionable if one should count wiiU as next gen at all.
