I agree that Nintendo has gotten me back into console gaming this generation; the things that they have done to completely blow my mind as if I were a kid again include:
-Mario Kart 8 being gorgeous, great soundtrack, one of the only racers this generation to still have 4-player split-screen, and a great example for what good DLC looks like.
-8-PLAYER SMASH!!!
-Everything they have done so far for Pokemon Alpha Sapphire/Omega Ruby
The kid in me has come back full force to most likely die from hype overload on Nov. 21st :)
Current Consoles: Gaming PC, Wii U, 3DS
