I'm a big fan of the WarioWare series, but this spin-off doesn't measure up to its predecessors. Only a very few of the games are any fun, and they get old pretty quickly. If you're looking for a fun collection of mini-games to showcase the Wii U's capabilities, I'd stick with "Nintendo Land".
I got the game expecting it to be another WarioWare masterpiece of adrenaline pumping micro games but I should have known it was going to be a collection of disappointing Mini games since it was named after Game & Watch. Only 1 game mode had some a few microgames that played exactly like WarioWare. Otherwise not a memorable or entertaining experience.
