WarioWare, Inc.: Mega Party Game$ (あつまれ!!メイド イン ワリオ, Atsumare!! Made in Wario) is the second game in the WarioWare series. It was the first WarioWare game released on a Nintendo home console. Instead of including different games than the Game Boy Advance game WarioWare, Inc.: Mega Microgame$, Mega Party Game$ included the exact same microgames, even with the same GBA graphics.
However, to make up for this, Mega Party Game$ becomes a multiplayer-oriented title. It truly becomes a "party game" by implementing the microgames in several "party" modes that up to 4 players can enjoy together. In most modes, the players compete with one another, to see who can last the longest, or who can complete the most microgames. Also, seven new mini-games have been added to have 4 players compete together.
In addition, you have the ability to play all of the microgames at the start, by going to a "library". Single player mode remains the same as the GBA version.
