Luigi's Manshon just came out a little bit ago! He's good for a selectable Character. Like in Mario Party, 2, 3, Gulf, Tennis, ect. He's also good as a second player in Mario games. It's also nice to give him a game once in a while. But he's not Nintendo's big star Mario is. I don't think I would like it if Luigi took over Mario.
(My two favorite worlds in Super Mario Brothers 3 are PipeLand and DarkLand. PipeLand is chalenging. It''s for experinced players. DarkLand is the final world. There is two Tanks, one LavaShip, and one DoomShip to go through before you get to Bowser''s Castle. Them two worlds are the most changing.) (Please join Mario Survivor in the Story Board)
