Nice, I'm not sure if there's already a thread about that, but no problem!
Personally, I'll have to say before all, I can't deny the fact that I would have loved to see a Wario Land based stage. However, this stage came out much cooler and an accurate representation of the WarioWare franchise! Not only the set is placed in a WarioWare level, but it also plays almost like the WarioWare games!
Randomly, you'll have a few minigames to play, some are from WarioWare Touched, others are from WarioWare Mega Microgame$, and some a just new or inspired by other micro games! Upon winning, you get a bonus, like a star or a mushroom, and upon losing, the game can shoot you out of the stage or you'll have to endure the other players with star power and giants! There's a cool detail too, if all players win the microgame, Wario makes a happy voice clip, like the WarioWare games, but if only one player fails the microgame, Wario will say a phrase like when he loses! Furthermore, if the WarioWare inc. theme is playing, each time a microgame appears, the music changes for the microgame! Wahahaha!
Even if I'm not as much of a fan of WarioWare as I am of Wario Land, this stage turned out to be so awesome! I'll say, better than the Game & Wario stage in the latest game.
