I've had the console for year now and I would say that it's good secondary console, as the library is not that diverse. Further, as for whole list "great" exclusives have been given on the thread apart from 3-4 like Mario 3d world, bayo2 and pikmin, rest merely fall into the good category. Some genres are like quality RPGs , sports , shooters are lacking.
But on the other hand the console looks good and the game pad has grown on me. Well in other words if ure a nintendo fan it's a must hv, if u are gaming mostly on PS/xbox then it's a decent secondary console, but don't expect it to take take over your living room. If you're mostly into RPGs then it's not worth it right now
