My fondest memories of my childhood aren't playing Contra or Street Fighter, but games like Chip N' Dale and Duck Tales.
The Wii U's game category has been much slower than others, but I feel like every single game Nintendo proper releases is pure gold, and there's plenty of 3rd-party games that have seen hundreds of hours of family gameplay (Rayman Legends).
Anyways, I hope this release brings about a new generation of Really Hard Mario levels!
