If they were going to go the route of giving Wario a new image, they should have at least done a format that wasn't already done to death. Don't even try to say the first WarioWare game wasn't based off Mario Party, the title even has "Party" in its name iirc.
While I gotta admit the idea of nothing but pits killing Wario in Wario Land 3 & 4 made no sense, it was still hella fun tackling enemies, riding Jet Pack hats, and breathing fire with the Dragon Hat.
In fact, I'd say Wario Land Wario would have a better moveset in Super Smash Bros Brawl than WarioWare Wario.
Neutral B: Dragon Wario
Up B: Jet Wario
Down B: Fart Attack (this can stay)
Smash B: Bull Wario Tackle
Final Smash: Wario Man (Master of Disguise was only bad because Wario's image was already tarnished by that factory)
