I honestly love WarioWare Gold, and it's weird how this was the era where Nintendo just wanted to make these kind of "celebration" type of games for their smaller IPs, seeing as they did the same with Rhythm Heaven.

WarioWare Gold is an extremely fun game full of different modes (with even one to dub cinematics), things to unlock, tons of microgames using all the mechanics from past Wario games, and a fully voiced story to add to it.
